Question

find the measure of each interior angle and each exterior angle of a regular 12 -gon (a twelve-sided polygon).

Answer 1

Interior=180 degree and exterior =360 degree

Answer 2

interior = 150° , exterior = 30°

Explanation:

the sum of the exterior angles of a polygon = 360°

since the polygon is regular then each exterior angle is

360° ÷ 12 = 30°

the sum of the exterior angle and interior angle = 180° then

interior angle = 180° - 30° = 150°
