Question

interior angle measure = 18x
exterior angle measure = 144 360/n
2x + 2°
3x + 8°
angles below:

Explanation:

Step1: Use vertical - angle property

Vertical angles are equal. So, we set up the equation \(2x + 2=3x + 8\).

Step2: Solve the equation for \(x\)

Subtract \(2x\) from both sides: \(2=x + 8\). Then subtract 8 from both sides: \(x=2 - 8=-6\).

Answer:

\(x=-6\)
