The exterior angle measure of a regular polygon is 20 degrees. How many sides does the polygon have?

Mathematics

Gwar [14]3 years ago

The polygon has 18 sides. To find an exterior angle you have to divide 360 by the number of sides in the polygon to find the measure of an exterior angle. Since each exterior angle equals 20 degrees, you would divide 360 by 20 which would equal 18 sides.
