Question

A convex hexagon has exterior angles of 54°, 38°, 41°, 64°, and 66°. What is the measure of an exterior angle at the sixth vertex?

Answer 1

Explanation:

Sum of external angles of a polygon is always 360°.

Sum of five external angles = 54° + 38° + 41° + 64° +66° = 263°

sixth external angle = 360° - 263° = 97°
