Sum of internal angles = (2n - 4)right angles, where n is the number of side and a right angle is 90 degrees. So we have here (30 - 4) x 90 degrees which is equal to

26 x 90 = 2340 degrees

Is interior angle angle sum?

No. An interior angle is one of many angles in the interior of a closed shape - usually a polygon. The angle sum is the sum of the values of a specified list of angles. They may be angles around a point, angles in one or more shapes.

What is the sum of the interior angles of a regular polygon if each angle measures 20 degrees?

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.

What is the sum of the angles of a pentagon?

For interior, the angle sum is 540 degrees, for exterior, the angle sum is 1260 degrees. * * * * * Partially correct! The sum of the exterior angles of any polygon is 360 degrees. The exterior angle is the supplement of the interior angle (180 - interior), NOT the reflex angle (360- interior). So the sum given 1260, which is based on the reflex angles is incorrect.
