Question

what is the value of x? (8x - 8)° (7x + 8)° drawing not to scale o 120 o 16 o -16 o 60

Explanation:

Step1: Set the two - angle expressions equal.

Vertical angles are equal. So, \(8x - 8=7x + 8\).

Step2: Solve for \(x\).

Subtract \(7x\) from both sides: \(8x-7x - 8=7x-7x + 8\), which simplifies to \(x-8 = 8\). Then add 8 to both sides: \(x-8 + 8=8 + 8\), so \(x = 16\).

Answer:

B. 16
