A pentadecagon is a 15-sided polygon.

 

Find the sum of the measures of the interior angles of a pentadecagon.  (Don't type the word degrees into your answer, just put the value.)

180(n - 2), where n = number of sides

 

This means the sum of the interior angles of a pentadecagon is:
180(15 - 2) 

= 180(13)
= 2340o
