Question 239990
<font face="Garamond" size="+2">


The sum of the interior angles of a convex *[tex \Large n]-gon is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (n\ -\ 2)(180)] degrees.


So, since you know the sum of the angles (2700) you can say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (n\ -\ 2)(180)\ =\ 2700]


Now all you need to do is solve for *[tex \Large n] to get the number of angles which is the same as the number of sides.  This works whether the polygon is regular or not.
