An interior angle of a 15-gon can have any measure between 0 and 360 degrees (excluding the two end values). The magnitude of an angle can only be determined theoretically (as opposed to measuring it) if it is a REGULAR polygon.
The sum of the interior angles of a polygon (regular or not) with n sides can be shown to be (n-2)*180 degrees. For a 15-gon this would mean (15-2)*180 = 13*180 = 2340 degrees.
If the polygon is regular, then each of the 15 angles is equal to 2340/15 = 156 degrees.

Each interior angle measures 108 degrees
What is the sum of the interior angle measures of a 15gon?
S of interior angles of ANY n-sided polygon is (2n -4) right angles, so 2 x 30 - 4 = 56, 56 x 90 = 5040 degrees
How can you get the measure of an interior angle if you have the measure of the exterior angle of a regular polygon?
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
What is the measure of an interior angle where the exterior angle measures 18 degrees?
Interior angle is 180 -18 = 162 degrees because there are 180 degrees on a straight line
What is the sum of the exterior angles of a non convex polygons?
