Question

If the measure of an exterior angle of a regular polygon is 120°, how many sides does the polygon have?

Answer 1

Measure of exterior angle = 360/number of sides

120 = 360/n

120n = 360

n = 360/120

n = 3


So there are 3 sides

Answer 2

ok, thanks you very much!

Answer 3

yw

Answer 4

hang on, would the formula be 360/n?

Answer 5

yes, if you have an n-gon, then the measure of one exterior angle is 360/n

Answer 6

ok ,thanks.
