Question

each interior angles of polygon is 120° .the polygon has blank side.
a.6
b.10
c.4
d.8

Answer 1

answer is 3 sides as its formula is 360 upon the number of sides

Answer 2

The interior angles are 120°, so the exterior angles are 180° - 120° = 60°. The exterior angles add up to 360°, so if we divide 360° by 60° we find there are 6 exterior angles. Therefore, there are 6 sides (it is a hexagon).
