Question 456232: the perimeter od a polygon is 72 feet. An exterior angle of the polygon is 30 degrees. what is the length of each side? so far i have 8(180)-360/8 to find the interior angle and i got 135 degrees which i dont think is right Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! the perimeter of a polygon is 72 feet. An exterior angle of the polygon is 30 degrees. what is the length of each side?
---
Fact: The sum of the exterior angles is 360 degrees.
---
I am going to assume the polygon is a regular polygon (all sides
are equal).
---
There are 360/30 = 12 exterior angles of size 30 degrees.
---
Therefore there are 12 equal sides.
---
The length of one side is 72/12 = 6 feet
