You can put this solution on YOUR website! The sum of all the interior and exterior angles of a polygon is 2880. how many sides does the polygon have?
----------------
The easy way:
2880/180 = 16
----------------
The hard way:
The sum of exterior angles is always 360 degs, so the sum of the interior angles is 2520 degs.
------------
sum of int = (n-2)*180 = 2520
n-2 = 2520/180 = 14
n = 16 sides
