Each exterior angle of a regular polygon measures 20 degrees. how many sides does the polygon have?

This polygon has 18 sides.

Step-by-step explanation:

We are given a regular polygon. Each exterior angle of this polygon is 20°.

We have to find the number of sides.

Sum of exterior angles of every polygon irrespective of number of its sides is

360°.

As it is a regular polygon, all exterior angles are equal and are of 20°.

Number of sides of polygon becomes = = 18
