The formula below gives the summer of degrees, S, of the interior angles of a polygon. if n represents the number of sides, which equation solves for n?

S = (n - 2) x 180

S/180 = n - 2

Its pretty obvious from here...

S = (n - 2) * 180

 

n = S/180 + 2  smiley

~~~~~~~~~~~~~~~~~~~~~~~~

If you are not sure what to do, use the real numbers:

 

S = (n -2) * 180                   S = 360       n = 4

 

360 = (4 - 2) * 180

 

4 = 360/180 + 2

 

4 = 4
