A 6 sided polygon is called a Hexagon. The sum of the interior angles or a regular hexagon is 720 degrees.
Total 1440o; if regular, each angle = 144o
A ten-sided regular polygon is a decagon. Total angles is 1440 degrees, with 144 degrees per angle.
156 degrees Sum of interior angles of a polygon=180(n-2), where n is the number of sides. To find one interior angle's measure, divide by the total number of angles, which is also the total number of sides.

Assuming it is regular, the total degrees of an n-sided polygon = 180(n-2) = 2700. 2700/17 = 158.23 degrees
The formula to calculate the TOTAL degrees of all angles in a shape is to use the formula(N-2) x 180 where N is the number of sides of that shape.So in this case:(12 - 2) x 18010 x 180 = 1800oThis means there is a total of 1800o in a 12 sided shape.Now since we know it's a regular shape, this means every angle making up this 12 sided shape will be the same. So this means we can divide the total number of degrees by 12. So:1800 / 12 = 150o is the size of one angle.I hope that helps.Jamz159
A hexagon (six-sided figure) has a total of 720 degrees. The formula is: n = number of sides (n - 2) * 180
The total interior angles add up to 1260 degrees.
The interior angles of any 8 sided octagon add up to 1080 degrees
