For the given right triangle, L = 66°, LK = 3.56, and the hypotenuse, LM = 8.75.
What is right triangle?A right triangle, right-angled triangle, or more formally an orthogonal triangle—previously known as a rectangled triangle—is a triangle with one angle that is a right angle (i.e., a 90-degree angle), meaning that two of its sides are perpendicular. The foundation of trigonometry is the relationship between the sides and other angles of a right triangle.
The hypotenuse is the side that faces the right angle (side c in the figure). Legs are the sides that are next to the right angle (or catheti, singular: cathetus). Side a can be thought of as the side that is adjacent to angle B and opposite to (or opposite) angle A, whereas side b is the side that is adjacent to angle A and opposite to angle B.
Given a right triangle with base = 8 and an angle = 24°
Using angle sum property of triangle
24 + 90 + angle L = 180
L = 66°
Using Sohcahtoa
Tangent: tan(θ) = Opposite / Adjacent
tan(24°) = LK/8
0.445 = LK/8
LH = 8 × 0.445
LK = 3.56
LM = [tex]\sqrt{MK^2 + LK^2}[/tex]
LM = [tex]\sqrt{8^2 + 3.56^2}[/tex]
LM = 8.75
Thus, For the given right triangle, L = 66°, LK = 3.56, and the hypotenuse, LM = 8.75.

The value of x is 39 and the values of angle m1 and m2 is 63 and 117. We can solve the question using linear pair.
What is linear pair?
When two lines meet at a single point, a pair of linear angles is created. If the angles follow the point where the two lines cross, they are considered to be linear pair. A linear pair's angles add up to 180° in every case. These angles are additionally referred to as. Angles with a shared vertex are those that are adjacent.
Therefore, the linear angles also have a common vertex in this instance.
Additionally, a common arm that symbolizes both angles will be present.
A ladder against a wall that creates linear angles at the ground is an example of a linear pair in real life. One who is straight is represented by linearity.
Using linear pair, we have equation
m1 +m2 = 180
x+24 +3x = 180
4x = 156
x = 39
Then the values of m1 =x +24 = 64

Solve the system of linear equations by graphing
y=-x+7
y=x+1
Answer: (3, 4)
Step-by-step explanation: Hello! To do this, you have to substitute one of the equations into the other. You know that in the first equation, y = -x + 7. Substitute -x+7 for y in the second equation. You now have -x + 7 = x + 1. Add x to both sides of the equation. -x + 7 + x = x + x + 1. You now have 7 = 2x + 1. Subtract 1 from both sides of the equation. You now have 6 = 2x. Divide both sides of the equation by 2. You now have 3 = x. The x-coordinate of where both linear equations intersect is 3. (3, y).
You now have to solve for the y-coordinate. To do this, look at your given equations. Subtract 2 from both sides of the second equation. You now have y - 1 = x. Substitute y-1 for x in the first equation. You now have y = -(y - 1) + 7. Simplify to get y = -y + 1 + 7. Add y to both sides of the equation. y + y = -y + y + 1 + 7. You now have 2y = 1 + 7. Add 1 + 7 to get 2y = 8. Divide both sides by 2 to get y = 4. You now know that the x-coordinate where both linear equations intersect is 3, and you know that the y-coordinate where both linear equations intersect is 4. Your answer is in the format of (x, y), which is (3, 4).

For what value of a the distance between the points 2 3 and 5 A is equal to 5?.
For a = 1 and a = -7, the distance between the points (2, -3) and (5, a) is equal to 5.
As we know according to the distance formula the distance between points (x₁, y₁) and (x₂, y₂) is given by,
[tex]d = \sqrt{[(x_2 - x_1)^2 + (y_2 - y_1)^2]}[/tex]
Here we have been given the distance between the points (2, -3) and (5, a)
Let us assume that (x₁, y₁) = (2, -3)
and (x₂, y₂) = (5, a)
Let d represents the distance between points (2, -3) and (5, a)
here d = 5 units
Using above distance formula,
[tex]\Rightarrow d = \sqrt{[(x_2 - x_1)^2 + (y_2 - y_1)^2]}\\\\\Rightarrow 5 = \sqrt{(5 - 2)^2 + (a -(- 3))^2}\\\\\Rightarrow 5 = \sqrt{(3)^2 + (a+3)^2}\\\\\Rightarrow 5^2=(3)^2 + (a+3)^2\\\\\Rightarrow 25=9+(a+3)^2\\\\\Rightarrow (a+3)^2=16\\\\\Rightarrow a+3=\pm 4[/tex]

Is Y =- 3 a horizontal line?.
So, Y = -3 is not a horizontal line but a vertical line.
A horizontal line is a line that runs along the x-axis and has a constant y-value. In the equation of a line, y = mx + b, a horizontal line has a slope of zero (m = 0) and a y-intercept of the constant value (b = constant).
The equation Y = -3 is not a horizontal line. This is an equation of a vertical line, which is a line that runs along the y-axis and has a constant x-value. In this case, the constant x value is -3.
A vertical line has no slope since it does not change in the x direction. The x-value is constant, which means the slope is undefined.
In a graph, a horizontal line can be represented by a straight line that is parallel to the x-axis, while a vertical line is represented by a straight line that is parallel to the y-axis.
To summarize, Y = -3 is not a horizontal line but a vertical line, which means that all the points on this line have the same x-coordinate (-3) and can take any value for y.

Find a principal which will amount to Rs.2000 in 6 years 8 months at the rate of interest 5% per annum.
Answer:
1449.28
Step-by-step explanation:
To find the principal amount that will amount to Rs. 2000 in 6 years 8 months at a 5% interest rate per annum, we can use the formula for compound interest:
A = P (1 + r/n)^(nt)
Where:
A = final amount
P = principal (the amount we are trying to find)
r = interest rate per annum (in decimal form)
n = number of times interest is compounded per year
t = time in years
In this case, the final amount is Rs. 2000, the interest rate is 5% per annum (or 0.05 in decimal form), the number of times interest is compounded per year is 1 (since the interest is compounded annually), and the time is 6 years 8 months (or 6.67 years in decimal form).So we can substitute these values into the formula and solve for P:
2000 = P (1 + 0.05)^(1 * 6.67)
To solve this equation, we can use a calculator or a spreadsheet to calculate the right side of the equation: (1+0.05)^6.67 = 1.382000 = P * 1.38
P = 2000/1.38
P = 1449.28
The principal amount that will amount to Rs. 2000 in 6 years 8 months at a rate of interest of 5% per annum is Rs. 1281.97.
The principal amount (P) that will amount to Rs. 2000 in 6 years 8 months at the rate of interest of 5% per annum can be calculated using the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = final amount
P = principal
r = rate of interest (5% per annum = 0.05)
n = number of times the interest is compounded per year (e.g. annually, semi-annually, quarterly)
t = time in years (6.67 years = 6 years 8 months)
Let's assume n = 12 (monthly compounding)
Substituting the values into the formula, we get:
2000 = P(1 + 0.05/12)^(12*6.67)
(To solve for P, we can divide both sides of the equation by the right side of the equation)
P = 2000 / (1 + 0.05/12)^(12*6.67)
P ≈ Rs. 1281.97
Therefore, the principal amount that will amount to Rs. 2000 in 6 years 8 months at a rate of interest of 5% per annum is Rs. 1281.97
It's important to note that this calculation is based on the assumption that the interest is compounded monthly, if the interest is compounded annually or semi-annually the amount will be different.

How do you sketch the graph of a function of two variables?.
A two-variable function's graph can be thought of as a surface in three dimensions.
The points (x, y, f(x, y)) where x and y are in the domain make up the graph of z=f(x, y). You can fine-tune the shape of the surface by drawing the curve k=f(x, y) in the plane z=k for different values of k. For instance, we're trying to comprehend the graph of z=f(x, y)=x2+y2. Keep in mind that k=f(x, y) is a circle for k>0 and since 0=x2+y2 implies that x=y=0.
Additionally, it is symmetric in relation to the z axis. We have a parabola for x=k or y=k. As a result, the graph represents the revolution of the parabola z=x2 over the z axis (see Thomas, math).

In the coordinate plane, if a line is drawn to connect two points (4, 2), and (8, 6), then the coordinates of the midpoint of the line joining these two points are ({4 + 8}/2, {2 + 6}/2) = (12/2, 8/2) = (6, 4).
What is midpoint?Midpoint refers to a point that is in the middle of the line joining two points. The two reference points are the endpoints of a line, and the midpoint is lying in between the two points. The midpoint divides the line joining these two points into two equal halves. Further, if a line is drawn to bisect the line joining these two points, the line passes through the midpoint.
The midpoint formula is used to find the midpoint between two points whose coordinates are known to us. The midpoint formula is also used to find the coordinates of the endpoint if we know the coordinates of the other endpoint and the midpoint. In the coordinate plane, if a line is drawn to connect two points (4, 2), and (8, 6), then the coordinates of the midpoint of the line joining these two points are ({4 + 8}/2, {2 + 6}/2) = (12/2, 8/2) = (6, 4).

-2(6c-3) = -72 : Answer is 6.5
Check left Side of both equations
Solve each equation in steps:
2(3b + 6) =78 Given3b + 6 = 39 Divide both sides by 23b = 33 Subtract 6 from both sidesb = 33/3 Divide by 3b = 11 Answer-2(6c - 3) = -72 Given6c - 3 = 36 Divide both sides by - 26c = 39 Add 3 to both sidesc = 39/6 Divide by 6c = 6.5 AnswerAnswer:
b = 11 c = 6.5Step-by-step explanation:
1) 2(3b + 6) = 78, value of b?
→ 2(3b + 6) = 78
→ 6b + 12 = 78
→ 6b = 78 - 12
→ 6b = 66
→ b = 66/6
→ [ b = 11 ]
Hence, the value of b is 11.
2) -2(6c - 3) = -72, value of c?
→ -2(6c - 3) = -72
→ -12c + 6 = -72
→ -12c = -72 - 6
→ -12c = -78
→ c = (-78)/(-12)
→ c = 78/12
→ [ c = 6.5 ]
Hence, the value of c is 6.5.
