The number of sides of a regular polygon whose interior angle is 156 degrees? 180 - 156 = 24 360/24 = 15

Exterior angle = 180-156 = 24 number of sides = 360 /24 = 15

External angle =180-156=24. Sum of external angle is 360 degrees. Number of sides will be 360/24=15.

The measure of each interior angle of an equiangular n-gon is (n - 2)180/n In this case 156 degrees is the measure of each internal angle: 156 = (n - 2)180 / n 156n = 180n - 360 360 = 24n 15 = n 15 sides

Assuming you mean interior ∠ Exterior ∠ = 24° Sides = 360/24 = 15

If the interior angle is 156 degrees, the exterior angle is 24 degrees Now, 360/24 => 15 sides :)>
