An Exterior Angle Of A Regular Polygon Is Four Times Smaller Than Its Interior Angle.how Many Sides Does The Polygon Have?
====
Let the interior angle be "4x".
Then the exterior angle will be "x".
---
Equation: x + 4x = 180
5x = 180
x = 36 degrees (measure of each exterior angle)
---
The sum of all of the exterior angles is always 360 degrees.
---
# of sides = # of exterior angles = 360/36 = 10
