Question

Find the measures of the exterior angles of the polygon.

Answer 1

D : 125°,125°,55°,55°

Explanation:

Finding the interior angles makes the question easier.

The two base angles for b1 are both 125°, and the two base angles for b2 are both 55°.

Because a straight line is 180°, we can find the exterior angles by subtracting the interior angles from 180°.

180°-55° = 125°

180°-125° = 55°
