Question

How many sides does a regular polygon have, if the measure of an exterior angel is 18°?

Answer 1

HEY mate here is your answer.

the polygon would have 20 sides.
we know that the sum of exterior angle of a polygon is 360°
so no of sides=360°\18=20°

hope it helps you.

Answer 2

The sum of exterior angles of a polygon = 360.

Given measure of an exterior angle = 18.

Number of exterior angles = 360/18

                                             = 20.


Therefore the number of sides = 20.



Hope this helps!
