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

2 answers:

6 0

Answer & Explanation:

Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. Let the number of sides be n. n = 18, an octadecagon.
