Remember
Exterior angle = 360 / No. of sides.
Hence
Exterior Angle = 360//25 = 24 degrees,
It follows that the intertiot angle is 180 - 24 =156 degrees.
There are 15 interior angles
Hence 15 x 156 = 2340 degrees is the sum of the interior angles of a 'Pentadecagon'.

What is the sum of the interior angle measures of a 25 - sided polygon?
The method of finding the sum of the interior angles of a polygon is by multiplying the (number of sides)-2 by 180, so the sum of the interior angle measures in a 25-sided polygon would be 23*180, or 4140 degrees.
