Question 564508: The sum of the measures of the interior angles of a polygon Is five times the sum of the measures of its exterior angles, one angle at each vertex. How many sides does the polygon have? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The sum of the measures of the interior angles of a polygon Is five times the sum of the measures of its exterior angles, one angle at each vertex. How many sides does the polygon have?
---
The sum of the exterior angles is ALWAYS 360 degrees.
--
So, sum of the interior angles is 5*360 = 1800 degrees.
----
Let n be the number of sides:
Equation:
(n-2)180 = 1800
n-2 = 10
n = 12 sides
