The length of the missing sides for given angles are
side a = 141.42135side b = 100side c = 1What is Pythagoras' Theorem?
Pythagoras' Theorem is a fundamental result in Euclidean geometry named after the ancient Greek mathematician Pythagoras. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
In other words, if a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse, then the theorem can be written as:
c² = a² + b²
tan A = a/c
c = a / tan A
We know that a = 100 and tan A = 100
so c = a / tan A = 100/100 = 1
We also know that b = 100
Now we can use the Pythagorean Theorem to find a:
a² + b² = c
100^2 + 100^2 = 1²
10000 + 10000 = 1
20000 = 1
a = sqrt(20000) = √(2000) × √(10) = 140.7107 × 10[tex]{}^{1/2}[/tex] = 141.42135
So,
side a = 141.42135
side b = 100
side c = 1

Give a brief account on Law of Coslnes?When the lengths of two sides and the size of the included angle are known (SAS) or when the lengths of all three sides are known (SSS), the Law of Cosines can be used to determine the remaining components of an oblique (non-right) triangle. We are unable to establish a solvable percentage in either of these scenarios, making it impossible to apply the Law of Sines.
According to the Law of Cosines:
c² = a² + b² - 2ab * cos(C)
With the exception of the third component, which equals zero if C is a straight angle and the Pythagorean Theorem results, this is similar to the Pythagorean Theorem. As a result, the Law of Cosines is a specific case of the Pythagorean Theorem.
Using the Law of Cosines
In the given triangle, we are given the measure of angle G and the length of side FG, so we can use the Law of Cosines to find the lengths of the other sides. The Law of Cosines states that for a triangle with sides a, b, and c and angle C opposite side c, the relationship between the sides and the angle is:
c² = a² + b² - 2ab * cos(C)
Given: angle G = 72°, FG = 6
We can use the Law of Cosines to find the lengths of the other sides:
EF² = FG² + GE² - 2FG * GE * cos(G)
EF = √(6² + GE² - 2 * 6 * GE * cos(72))
FG² = EF² + GE² - 2EF * GE * cos(F)
FG = √(EF² + GE² - 2 * EF * GE * cos(66))
As we don't have any value for GE, we can't calculate the exact values, but as we know that the side opposite to the largest angle is the longest side of a triangle, so we can order the sides as follows:
EF < FG < GE
It means that side GE is the longest side of the triangle, followed by side FG, and side EF is the shortest side of the triangle.

Find the smallest positive integer b for which x^2+bx+2008 factors into a product of two binomials, each having integer coefficients.
Answer:
b = 259
Step-by-step explanation:
You want the smallest positive 'b' that makes x² +bx +2008 have integer solutions.
FactorsWhen the polynomial is factored, you have ...
(x +p)(x +q) = x² +(p+q)x +pq
Comparing this to the given expression, we see that ...
p + q = b
pq = 2008
This means the values of p and q will be divisors of 2008.
Factor pairsThe positive integer factor pairs of 2008 are ...
2008 = 1·2008 = 2·1004 = 4·502 = 8·251
The pair with the smallest sum is 8·251. The corresponding sum is ...
8 +251 = 259
The smallest positive value of 'b' that makes x² +bx +2008 have integer solutions is 259.

Additional comment
The factorization is x² +259x +2008 = (x +8)(x +251).
I came across a question in the pigeonhole principle that – Let S be a set of n integers. Show that there is a subset of S, the sum of whose elements is a multiple of n by pigeonhole.
How do I solve this question??
In this case the difference is a multiple of n and as you see the difference is still a sum of some integers subset from 1 to n
What is subset?
If every element of set A is also an element of set B, then set B is a superset of set A and set A is a subset of set B. A and B could be equal; if they are not, then A is a legitimate subset of B. Include refers to the property that one set is a subset of another.
Consider the set{a1,a1+a2,a1+a2+a3,...,a1+a2+...+an}You have a set of n elements .If all remainders in dividing by n, are different, one of the remainders is 0 and we are done .Otherwise two remainders are the same.
In this case the difference is a multiple of n and as you see the difference is still a sum of some integers from 1 to n However I think it would be natural to consider the set{0,a1,a1+a2,a1+a2+a3,…,a1+a2+⋯+an}of n+1 elements, so that there is only one case instead of two.

Given: GH is parallel to KL; GJ is congruent to KJProve: J is the midpoint of HLThe shape is an hour glass figure. GH on the left side J in the middle and LK on the right side.
The distance between J and L is (Gx/2)2 + (Gy/2)2. This proves that J is the midpoint of HL.
Given: GH is parallel to KL and GJ is congruent to K
To prove: J is the midpoint of HL
We can use the Midpoint Formula to prove that J is the midpoint of HL. The midpoint formula states that the midpoint of a line segment is the average of the x-coordinates and the average of the y-coordinates. In this case, the x-coordinate of J is (Gx + Kx) ÷ 2 and the y-coordinate of J is (Gy + Ky) ÷ 2. Since GH and KL are parallel, Gx = Kx and Gy = Ky. Therefore, the x-coordinate of J is (Gx + Kx) ÷ 2 = Gx ÷ 2 and the y-coordinate of J is (Gy + Ky) ÷ 2 = Gy ÷ 2. Since GJ is congruent to KJ, Gx = Kx and Gy = Ky. Therefore, J is the midpoint of HL.
We can also use Distance Formula to prove that J is the midpoint of HL. The distance formula states that the distance between two points is the square root of the difference of the x-coordinates squared plus the difference of the y-coordinates squared. In this case, the distance between G and J is the square root of (Gx - Jx)2 + (Gy - Jy)2. Since GJ is congruent to KJ, Gx = Kx and Gy = Ky. Therefore, the distance between G and J is the square root of (Gx - Jx)2 + (Gy - Jy)2 = (Gx - Gx/2)2 + (Gy - Gy/2)2 which simplifies to (Gx/2)2 + (Gy/2)2. This is the same distance as the distance between J and L, since GJ is congruent to KJ, Gx = Kx and Gy = Ky. Therefore, the distance between J and L is (Gx/2)2 + (Gy/2)2. This proves that J is the midpoint of HL.

What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
From the given graph, zeros are x=2, x=1, x=-1 and x=-4.
The equation of a polynomial having x intercepts a₁,a₂,…,aₙ is [tex]P(x)=a(x-a_1)^{P_1}(x-a_2)^{P_2}....(x-a_n)^{P_n}[/tex].
Where P₁,P₂,…,Pₙ are the powers of the factors of the polynomial, which depend upon the behavior of the graph of the polynomial.
At this point x=-1, x=-4 and x=1 the graph passes through the axis linearly, therefore, the corresponding factor of the polynomial must be linear.
At x=2, the behavior of the polynomial is bouncing in nature, suggesting the corresponding factor of the polynomial having a second degree.
Now, the equation of the polynomial can be written as shown below:
P(x)=a(x+1)(x+4)(x-1)(x-2)²
The polynomial passes through the point (0, 2), therefore
2=a(0+1)(0+4)(0-1)(0-2)²
2=a(1)(4)(-1)(4)

what value will make 7x +ky =35 parallel to 5x-3y+44=0
The value of k that makes the line 7x + ky = 35 parallel to the line 5x - 3y + 44 = 0 is k = -21/5.
How to solve the parallel equation?Two lines are parallel only if their slopes are the same. The slope of a line of the form y = mx + b (where m is the slope and b is the y-intercept) is m. The slope of a straight line of the form ax + by + c = 0 can be found using the formula: The calculation formula for the slope cutting shape will change.
So to find the value of k that makes the line 7x + ky = 35 parallel to the line 5x - 3y + 44 = 0, we need to find the slope of the line 5x - 3y + 44 = 0. To do this, we rearrange the equation into slope-intercept form.
5x - 3y + 44 = 0
-3y = -5x + 44
y = (5/3)x - 14.67
The straight line 5x - 3y + 44 = 0 has a slope of 5/3. In order for the 7x + ky = 35 line to be parallel to this line, the slope of 7x + ky = 35 must also be 5/3. To find the slope of 7x + ky = 35, rearrange the formula into slope-intercept form.
7x+ky=35
y = -(7/k)x + 35/k
Setting the slope of the line 7x + ky = 35 equal to the slope of the line 5x - 3y + 44 = 0 gives:
-(7/k) = 5/3
-7/k = 5/3
-7 * 3 = 5 * k
-21 = 5k
k = -21/5
Therefore, the value of k that makes the line 7x + ky = 35 parallel to the line 5x - 3y + 44 = 0 is k = -21/5.

at times, the relationship between a dependent and an independent variable is expressed as a logarithmic equation. given the two equations below, what is the relationship between x and y? equation 1: log36
The relationship between x and y as a logarithmic equation is: y = log_36 9 = 2.
The relationship between x and y can be expressed as a logarithmic equation. Let's take a look at the two equations:
Equation 1: log36
To calculate the relationship between x and y, we will use the logarithmic property: logb(x) = y ⇔ b^y = x
From equation 1, we can solve for y:
log36 = y
⇒ 36^y = 36
⇒ y = 1
Therefore, the relationship between x and y is: x = 36^1 = 36.
To verify this, we can plug x = 36 into equation 2 and see if it is true:
Equation 2: y = log_x 9
Plugging in x = 36, we have:
y = log_36 9
⇒ y = log_36 3^2
⇒ y = 2
Therefore, the relationship between x and y is: y = log_36 9 = 2.
This confirms that the relationship between x and y is x = 36 and y = 2.

The circle
Using the following theorem
The measure of the angle formed by two chords that intersect inside a circle is equal to half the sum of the measure of their intercepted arcs
We have the following equation
1/2(y + 163) = 124
So, we have
y + 163 = 248
Evaluate the like terms

Can somebody help me? I am learning about Basic Exponent Properties in Algebra and I do not understand how to solve equations with exponents. Please tell me how to do it?
Here are some examples:
1. (4xy²)(-2x²y³)
2. 6y³/18x · 2xy
3. Which expression has the greater value? 2³ · 2(exponent 5) or 4(exponent 7)/4³
4. (3x)exponent1/3 · (3x)exponent7/3 / (3x)exponent2/3
Please Answer ASAP!! I will give 40 points!!
Answer:
Provided an explanation below.
The examples are not asking you to solve, only to simplify the expression
For the examples you posted, not sure if you want the solutions are not; I have gone ahead and simplified
[tex]1.\; -8x^3y^5\\\\2\; \dfrac{2y^3}{3}\\\\3.\; They are both equal\\\\4.\; 3x^2\\\\[/tex]
Step-by-step explanation:
First let's understand what an exponent is.
When a number or a term or an expression is multiplied repeatedly by itself, an exponent can be used to represent this situation
for example,
5 x 5 x 5 x 5 x 5 x 5 = 5⁶ since 5 is multiplied by itself 6 times
Here the number being multiplied(5) is called the base and the number of times it is multiplied(6) is called the exponent.
There are some rules regarding exponentiation
1 Zero Exponent
Any number raised to the power zero is 1
[tex]4^0 = 1\\\\123.456^0 = 1\\\\x^0 = 1[/tex]
2. Negative Exponent
If the exponent if negative, the expression is equivalent to the reciprocal of the term raised to the positive exponent
In general
[tex]a^{-m} = \dfrac{1}{a^m}\\\\and\\\\\dfrac{1}{a^{-m}} = a^m\\\\[/tex]
Examples:
[tex]x^-1 = \dfrac{1}{x}\\\\\left({x + y}\right)^{-a} = \dfrac{1}{(x+y)^a}[/tex]
[tex]\dfrac{1}{x^{-3}} = x^3[/tex]
3. Product Rule
When you multiply exponents with the same base the exponents get added
In general
[tex]\displaystyle {a^m a^n = a^{m + n}}[/tex]
Examples
[tex]x^3x^6 = x^{(3+6)} = x^9\\\\[/tex]
4. Quotient Rule
When you divide an exponentiated term by another exponentiated term with the same base the resulting exponent is the difference between the two exponents:
In general
[tex]\dfrac{a^m}{a^n} = a^{m-n[/tex]
Examples
[tex]\dfrac{y^3}{y^2} = y^{3-2} = y^1 = y[/tex]
5. Power Rule 1
An exponent term raised to another power will be the base raised to the product of the two exponents
In general
[tex](a^m)^n = a^{mn}[/tex]
[tex](x^3)^4 = x^{3 \cdot 4} = x^{12}[/tex]
6. Power Rule 2
If the base is the product of two or more terms and the whole expression is raised to a power then each individual term gets raised to that power.
[tex](ab)^m = a^mb^m\\\\(2x^3y^2z^4)^4 = 2^4x^{3.4}y^{2.4}z^{4.4} = 16x^{12}y^8z^{16}[/tex]
7. One exponent
Any term raised to the power 1 is itself
[tex]a^1 = a[/tex]
example: 5¹ = 5
x¹ = x
You may have to use some or all of the rules when confronted with a specific problem
There are plenty of excellent resources on the web which can explain far more lucidly than I can.
Here are a few. Just search for them and you will get the site links

The best strategy for Alice is to take the card with the highest point value. This will maximize her chances of winning, since she can then choose the last card from the remaining cards. Bob should take the card with the lowest point value, as this will minimize Alice's chances of winning.
Alice always takes the first turn. Bob can either take the leftmost card or the rightmost card. If Alice takes the leftmost card and Bob takes the rightmost card, then Alice will have the advantage of being able to make the last move. If Bob takes the leftmost card and Alice takes the rightmost card, then Bob will have the advantage of being able to make the last move.
The best strategy for Alice is to take the card with the highest point value. This will maximize her chances of winning, since she can then choose the last card from the remaining cards. Bob should take the card with the lowest point value, as this will minimize Alice's chances of winning.
Alice should also be aware of Bob's strategy and try to anticipate what card he will take. If Alice can guess correctly, she can adjust her strategy to ensure she takes the card with the highest point value. If she guesses incorrectly, she should still attempt to take the card with the highest point value.
Alice should take the card with the highest point value and Bob should take the card with the lowest point value. Alice should also anticipate Bob's strategy and adjust accordingly to ensure she takes the card with the highest point value.
