3. Hexagon

Pls answer it correctly. need it tomorrow!​

Answer 1

120° , 45° , 60°

Explanation:

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

the exterior angles of a regular polygon are congruent , then

(1) triangle with 3 sides

exterior angle = 360° ÷ 3 = 120°

(2) octagon with 8 sides

exterior angle = 360° ÷ 8 = 45°

(3) hexagon with 6 sides

exterior angle = 360° ± 6 = 60°
