Question

the difference between the interior angle and exterior angle at each vertex of a regular polygon is 162 degrees.Find the number of sides of the polygon

Answer 1

Answer:

(n-2)•180/n = A where N is the Side of the Polygon and A is the Angle of the Polygon , then A = 162

(n-2)•180/n = 162

Solve for n

n = 20

There are 20 sides of the Polygon
