Question

A regular polygon has 40 sides.
Find the size of each of its interior angles.

Answer 1

An interior angle of a polygon is found by subtracting 2 from the number of sides, multiplying that by 180 And then divide by the number of sides:

40-2 = 38

38 x 180 = 6840

6840/40 = 171

Answer : 171 degrees
