If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.

999999

40 sides

Each interior angle of the regular 8 sided octagon measures 135 degrees

It will have 10 equal sides

that's geometry so the formula to find the measure of each interior angle of a regular polygon is: Ia=stands for internal angle Ia=(n-2)180 ---------- n that's the formula.

180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle

Each interior angle: 140 degrees Each exterior angle: 40 degrees

360/number of sides and deduct the quotient from 180 which will give the measure of each interior angle

AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. Once you have the sum, divide by the number of sides to find an individual angle.

It is: (number of sides -2)*180 = sum of interior angles If its a regular polygon then: sum of interior angles/number of sides = each interior angle
