Question 403248
What is the number of sides of a regular polygon if each interior angle measure is 5 times the measure of each exterior angle
---
An interior/exterior pair is supplementary.
x + 5x = 180
6x = 180
x = 30 (the exterior angle)
=====
The sum of all the exterior angles is 360.
----
# of exterior angles is 360/30 = 12
----
Therefore # of sides = 12
