Answer:
x = 27
Explanation:
Since they are corresponding they have to be equal.
4x+7 = 5(x-4)
4x+7 = 5x-20 distribute the 5
7 = 5x-4x-20 bring the 4x over
7 = x-20 simplify the x
7+20= x bring the twenty over
27=x
27 =x
The two angles are vertical angles and vertical angles are equal
Distribute
4x+7 = 5x-20
Subtract 4x from each side
4x+7-4x = 5x-4x-20
7 = x-20
Add 20 to each side
7+20 = x-20+20
