Question

Given the measure of each interior angle of a regular polygon, find the number of sides of the polygon
a. 140 degree​

Answer 1

Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.

Answer 2

Answer:

A polygon has 5 sides

Explanation:

formula to find each interior angle of any figure

(n-2)×180 { where 'n' is number of sides }

(5-2)×180

= 3×180

= 540° is the sum of all the interior angles of the polygon.

= 540\5 = 18° each interor angle og the polygon.
