<PRE><B>Question 193886</B>
One exterior angle of a regular polygon measures 24 degree.What is the sum of measures of its interior angles of a polygon?
--------------------
The sum of the exterior angles of any regular polygon is 360 degrees.
Since you have a 24 degree angle there are 360/24 = 15 sides and 
15 interior angles.
-------------
Each interior angle is the supplement of its exterior angle.
The supplement of 24 is 180-24 = 156 degrees.
------------
The sum of the interior angles is 15*156 = 2340 degrees.
