Question

find the measure of each of the exterior angles of a regular polygon of
a) 8 sides
b) 10 sides

find the measure of each of the interior angles of a regular polygon of
a) 12 sides
b) 18 sides

Answer 1

a. 8 sides = 360°/8 = 45°
b. 10 sides = 360°/10 = 36°

a. 12 sides = (12-2)180°/12 = 150°
b. 18 sides = (18-2)180°/18 = 160°
