Vertical angles are congruent or equal to each other.

Set the equation:

8x - 8 = 7x + 8

Add 8 to both sides of the equation.

8x - 8 + 8 = 7x + 8 + 8

8x = 7x + 16

Subtract 7x from both sides of the equation.

8x - 7x = 7x - 7x + 16

x = 16

Answer: D) 16

Checking to see if our answer is right.

8x - 8 = 7x + 8

8(16) - 8 = 7(16) + 8

128 - 8 = 112 + 8

120 = 120
