Sum_of_interior_angles = (number_of_sides - 2) × 180°
→ for a 30-gon sum = (30 - 2) × 180° = 5040°
each angle is (n-2)/n times 180 degrees where n is number of sides.angle = 28/30 x 180 = 168 degreessum of all 30 angles is 30 x 168 = 5040 degrees
the interior angle of a 7 sided regular polygon is 128.57 degrees
The sum of the interior angles of a 14 sided polygon are 2160 degrees.
3240
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees
540 degree for the interior angles
A 29-sided polygon.
the interior angle of a 7 sided regular polygon is 128.57 degrees
The sum of the interior angles of a 14 sided polygon are 2160 degrees.

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.
The interior angles of a 15 sided polygon add up to 2340 degrees
sum of interior angles of EVERY n-sided polygon is 180n - 360 degrees. When n = 15 sum is 2340 degrees.
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees
The 13 interior angles of a 13 sided polygon add up to 1,980 degrees
The sum of the three INTERIOR angles is 180 degrees. And a 3-sided polygon is often referred to as a 'Triangle'.
