Answer:
17
Step-by-step explanation:
angle one and angle three are equal to each other
so if you set the equations equal to each other
(4x+2)=( 5x-15)
move the 4x the right by subtracting it giving you 1x
then add 15 to 2 giving you 17
17=1x

Solve the expressions in parentheses first.
There is an expression within parentheses that is also in an expression within brackets. Solve that expression first:

The expression in brackets will now read:
![[4 - 3(-4)]](https://tex.z-dn.net/?f=%20%5B4%20-%203%28-4%29%5D%20)
Multiply 3(-4):

![[4 - (-12)]](https://tex.z-dn.net/?f=%20%5B4%20-%20%28-12%29%5D%20)
Solve the expression:

The problem should now look like this:

Solve the expression in parentheses that has an exponent:


Solve the term with 1/4 as a coefficient:

The expression should now look like this:

The answer is 40.
(-2,4) (0,4) (-2,7) are the co ordinates
D 7.5,5 , and C h. = 45d
I hope this help
