What is the sum of the interior angles for a 15 sided figure?
The sum of the interior angles of any polygon is equal to (n - 2) x 180 degrees. in this case, (15 - 2) = 13 x 180 = 2340 degrees.Therefore, the sum of the interior angles of a 15-sided figure (a pentadecagon) is 2340 degrees.
What is the sum of the exterior angles of an eight sided figure?
The sum of the angles of an 8 sided octagon add up to 360 degrees
What is the degree sum of a ten sided shape?
The sum of a 10 sided figure is 1440 To solve it or the sum of any other figure you do this... 180(n-2) n equals the number of sides the figure has 180(10-2) 180(8) 1440

What is the sum of the interior angles of an 8 sided figure?
The sum of the interior angles of an n sided figure is (n-2)*180 degrees So for an 8 sided figure, the sum is 6*180 = 1080 degrees.
What is the sum of a nine sided figure?
