How many sides does a regular polygon have if the measure of one interior angle is 160 degrees?
The exterior angles are 20º
n = 360/20 = 18 sides

----
The corresponding exterior angle is 180-160 = 20
---------------
Fact: The sum of ALL the exterior angles is 360
---
Your Problem:
# of exterior angles is 360/20 = 18
---
# of sides = # of exterior angles = 18
