Answer:
B. 66 degree
Step-by-step explanation:
We know
A triangle is 180 degrees. Angle B is 27 degrees, and angle C is 87 degrees. To find angle A, we take
27 + 87 = 114 degree
180 - 114 = 66 degree
So, the answer is B. 66 degree
hey I need help with this two step equation!! m/3-7=1
Answer:
m = 24
Step-by-step explanation:
To solve the equation m/3-7 =1, we can start by isolating m on one side of the equation. To do this, we will add 7 to both sides of the equation:
m/3 - 7 + 7 = 1 + 7
m/3 = 8
The next step is to multiply both sides of the equation by 3 to get rid of the fraction:
m/3 * 3 = 8*3
m = 24
So the solution to the equation is m=24

What is the Pythagoras theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².
Given here: A quadrilateral WXYZ with ∠Z=75 and ∠X=105
Let P be a point on ZW such that ZP=x and WP=4-x, then we form a right-angled triangle ΔZPY with tan 15°=x/PY
∴ PY=x/tan 15
=3.732x
Now using Pythagoras' theorem we get ZY as
[tex]\sqrt{13.927x^2+x^2} \\=\sqrt{14.92x^2}\\ =3.862641x[/tex]
Now let's connect the diagonal ZX we get the right triangle ZWX
Thus using Pythagoras' theorem we get
ZX=[tex]\sqrt{4^2+4^2}[/tex]
=4√2
Again let Q be an extension such that YQ=4-x & ∠YXQ=75°
Thus Sin 75=4-x/√N
√N=4-x/0.965923
squaring both sides we get N=(4-x)²/0.9330127........(1
Now using the Pythagoras theorem in ΔZYX we get
√N=
[tex]\sqrt{ZX^2-ZY^2} \\=\sqrt{32-14.92x^2} \\[/tex]
⇒N=32-14.92x²..,.......2)
Thus equation two values of N we get
(4-x)²/0.9330127=32-14.92x²
16-8x+x²=29.8564-13.920549x²
14.921x²-8x-13.856=0
Thus using the quadratic formula we get the value of x as
x= 8±29.85 /29.84
x=1.2684 (∵ Distance cannot be negative)
∴ Value of N=32-14.92×1.2684
N=13.075
√N=3.6159
Hence, The value of √N is 3.16159

Answer:r=175 this is for IXL I hope this helps
Step-by-step explanation:
r/-25 =-7
Multiply both sides of the equation by -25
-25 times r/-25=-25 time (-7)
Multiplying two negatives equals a positive: (-) times (-) =(+)
25•r/25=-25•(-7)
then
Cancel out the greatest common factor 25
R=-25 times (-7)
Also Multiplying two negatives equals a positive: (-) times (-) =(+)
r=25 times 7
Multiply the numbers 25•7
Then you get
R=175
How do you write greater than 35?.
The correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.
In mathematics,
→The greater than symbol (>) is used to indicate that one value is larger than another. For example, if we say "A > B," this means that the value of A is greater than the value of B.
→The less than symbol (<) is the opposite, it indicates that one value is smaller than another. For example, if we say "A < B," this means that the value of A is less than the value of B.
→The greater than or equal to symbol (≥) indicate that one value is larger than or equal to another. For example, if we say "A ≥ B," this means that the value of A is greater than or equal to the value of B.
→The less than or equal to symbol (≤) indicate that one value is smaller than or equal to another. For example, if we say "A ≤ B," this means that the value of A is less than or equal to the value of B.
These symbols are commonly used in mathematical expressions, equations, and inequalities.
To write "greater than 35" in mathematical notation, you would use the greater than symbol (>) followed by the letter 35. For example:
A > 35
This means that A is greater than 35.
Therefore, the correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.

What is additive comparison?
In an additive comparison, we question or state how much more (or less) one amount is in contrast to the other to determine the relationship between the two numbers. Additive comparison issues are typically word problems that can be resolved by creating an equation.
The comparison approach is a technique for rewriting each equation with the same variable as the subject in order to solve systems of independent equations. The initial variable to isolate can be any of the variables. Every equation is now an isolated-subject equation with an isolated variable.
Let,
if in about x month, the population of the towns will be equal .
the equation will be;
70,000 + (150-100)x = 61,000 - 200x
⇒ 70,000 + 50x = 61,000 - 200x
⇒ 250x = 9000
⇒ x = 9000/250
⇒ x = 36
So, in 36 months the populations of the 2 cities be the same .

What is the factor of the polynomial a2 2ab b2?.
The factors of polynomial a² - 2ab + b² is equals to the (a - b)², that is (a -b) and (a-b).
To determine the factors we can use the concept of splitting the middle terms and first making the pair of two terms and then finding the common factors from the paired terms and finally the factors for the expression. We have an expression, a² - 2ab + b². Using the concept of to split the middle term. As we see there is three terms in the expression.
Now, multiply the coefficient of first term with the cofficient of last term, i.e., 1 × 1 = 1 Split the middle term cofficient, that is -2 such that sum or difference of spliting terms is -2 and multiplication become 1. Use the basic concept of the product of two negative values results positive value and addition of two negative values provide negative sign, so (-1)(-1) = 1 and -1 + (-1) = -2.Thus, we can rewrite the expression as
=> a² - ab - ab + b²
Make the pair of two terms in the above expression, (a² - ab) - ( ab - b²).
Take common factors from the paired terms,
=> a(a - b) - b(a - b).
Take the common factors in the above equation => (a - b) (a - b)
=> (a - b)¹⁺¹ = (a + b)²
Hence, factor of a² - 2ab + b² is (a-b)² i.e., (a - b) and (a - b).

How much is all 3 angles of a triangle?.
All 3 angles of a triangle always add up to 180 degrees.
This is because a triangle is a three-sided polygon and the sum of the angles in any polygon is always 180 degrees multiplied by the number of sides minus 2. Therefore, in a triangle, which has three sides, the sum of the angles is 180 x (3-2) = 180 degrees. This rule is known as the "triangle angle sum theorem" and is a fundamental property of triangles. It is important to note that this rule applies to all types of triangles, whether they are right triangles, acute triangles, or obtuse triangles.
