Answer:
Step-by-step explanation:
you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines. so you can say
180 = (6x + 5) + (3x+13)
180 = 9x +18
162 = 9x
18 = x
Answer:
Solution given;
6x+5+3x+13=180(sum of exterior angle is 180°)
9x=180-18
x=162/9
x=18 is a required answer.

Answers
Answer:
m∠b=m∠c=61°
Step-by-step explanation:
The 119° angle and ∠b/∠c are supplementary angles. ∠b and ∠c are congruent because they are vertical angles and they are also both supplementary to the 119° angle. I will use b to find c.
[tex]b+119=180[/tex]
[tex]b=61[/tex]
Since b and c are equal, c=61 too.
What is the value of y?
Answers
Answer and Step-by-step explanation:
We are given a triangle and are asked to solve for the value of y.
We know that the angles in a triangle add up to 180 degrees. So let's add all of the angles together and equal it to 180.
2y + y + 10 + 50 = 180
Combine like terms.
3y + 60 = 180
Now subtract each side by 60.
3y = 120
Finally, divide each side by 3.
y = 40
We get the value of y to be 40.

THE CORRECT ANSWER IS B- 73 FEETThe given condition in question will form a right angle triangle
and the length of sides of triangle are given 55ft, 48ft and missing one.
Now using pythagoras theorem,55²+48²= x²
x² = 3025 + 2304
x² = 5329
Taking square root of 5329 will give 73 ft!

Given:
The function is:
[tex]f(x)=-2x+5[/tex]
To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,
[tex]f(x)=-2x+5[/tex]
Step 1: Substitute [tex]f(x)=y[/tex] .
[tex]y=-2x+5[/tex]
Step 2: Interchange x and y.
[tex]x=-2y+5[/tex]
Step 3: Isolate variable y.
[tex]2y=5-x[/tex]
[tex]y=\dfrac{5-x}{2}[/tex]
Step 4: Substitute [tex]y=g(x)[/tex].
[tex]g(x)=\dfrac{5-x}{2}[/tex]
Hence, the inverse of the given function is [tex]g(x)=\dfrac{5-x}{2}[/tex] and the graphs of these functions are shown below.

What is the area, in square inches, of the isosceles trapezoid below?
Answers
Explanation-
14.2 - 6.4 = 7.8 (to get the length of the base without the top part)
7.8 • 5.2 = 40.56 (to find the area outside of our subtracted square that has the top part)
6.4 • 5.2 = 33.28 (to find the area of the inner square)
40.56 + 33.28 = 73.84 (adding together both parts to find the total area)
A = 73.84
