Question 286283: how many sides does a polygon have if it 540 degrees

Answer by dabanfield(803) (Show Source): You can put this solution on YOUR website!
Use the theorem that says that if n is the number of sides of a polygon the sum of the interior angles is (n-2)*180.
So we have:
(n-2)*180 = 540
180n - 360 = 540
180n = 540 + 360
180n = 900
n = 5
