The formula for finding the sum of the interior angles of a polygon is:
180 x (n - 2) where n = the number of sides.
This comes from knowing the following: Given a polygon of n sides, there are n - 2 triangles you can form by connecting a given vertice (point where two sides meet) to all other vertices of the polygon. The 180 in the formula is the sum of the angles in a triangle.
Therefore, the sum of the interior angles (or, as you put it, the angle sum) of your 11 sided figure would be:
180 x (11 - 2) = 180 x (9) = 1620 degrees.

The sum of the interior angles of a 14 sided polygon are 2160 degrees.
the interior angle of a 7 sided regular polygon is 128.57 degrees
3240
The sum is 540 degrees, each angle being 108 degrees.In general, in an n-sided polygon, the sum of the angles is 180 (n-2).
540 degree for the interior angles
No because the closest polygon sum is 1620 which is the hendecagon the eleven sided polygon

A 29-sided polygon.
Sum of exterior angles of any sided polygon is 360 so sum of exterior angle of 6 sided polygon (hexagon) is 360
1620

The sum of the interior angles of a 14 sided polygon are 2160 degrees.
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)

2700 degrees
1080 degrees
No Kele is not because the nearest answer is 1620 the eleven sided figure
