Question 503513
Can you please help me with this question. The measure of each interior angle of a regular polygon is three times the measure of each exterior angle. How many sides does the polygon have? 
---
Each exterior/interior pair are supplementary.
Let the exterior angle be "x".
---
x + 3x = 180
4x = 180
x = 45 degrees
----
The sum of all the exterior angles is 360 degrees.
---
# of exterior degrees = 360/45 = 8
---
# of sides = # of extgerior angles = 8
