Problem says: Find the number of sides this polygon has by knowing the that one exterior angle ='s 20? How do I go about working this problem?
-
The sum of the exterior angle of a polygons add up to 360 degrees
If all the angles are equal then 360 degrees/ 20 degrees = 18 sides.
If all the angles are equal then 360 degrees/ 20 degrees = 18 sides.
