What is the sum of the interior angles of a 8 sided polygon?
The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon. An octagon has eight sides, so the sum of the angles of the octagon is 180(8 – 2) = 180(6) = 1080 degrees.
How many sides does a polygon have if the sum of its interior angles is 360?
n = the number of sides of the polygon. the polygon has 17 sides. 17 * 21.17647059 = 360 degrees which is should since the sum of the exterior angles of a polygon is always 360 degrees.

How do you find the sum of the interior angles of a polygon with 7 sides?
1 Answer
- sum of angles = (n – 2) × 180.
- sum of angles = (7 – 2) × 180.
- sum of angles = 5 × 180.
What is the sum of the interior angles of a polygon having 9 sides?
So the interior angle of a 9 -sided polygon is 140 ° . We can see that x and one interior angle lie on the same side of a straight line, so their sum must be 180 ° . So x = 180 ° − 140 ° , or x = 40 ° . The correct answer is 40 ° .
