(n-2)*180 = (6-2)*180 = 4*180 =720
polygon with 17 sides
A dodecagon
The angle sum of a polygon is always 360 degrees. If all angles are equal, then each angle is 18 degrees. Simply divide 360 by 20.
There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.

The question has been asked "What is the angle sum of a thirteen sided polygon?" The answer to this question is 1980 degrees. The sum of the interior angles of a polygon of n sides = 180(n - 2)
it depends what kind of polygon but the sum of the angles will equal a # divisible by 90
1440 degrees
