We can solve this more quickly by finding the exterior angles of each n-gon. Note that the sum of the exterior angles in any convex polygon is 360 degrees. Given an interior angle, we can find the exterior angle by using 180 - x, where x is the interior angle measure.

Therefore, use the equation (substituting values for x) to find the value of n. For part a),

, therefore it is an 8-sided polygon. Repeat for the other three measures.
