Question

if the polygon has interior
162° .then how many sides the polygon has.. please say me step by step​

Answer 1

The exterior angle is 18°. The sum of all exterior angles is 360°.

The regular polygon will have 20 sides.

Alternatively,

Use the formula : Total of all interior angles of polygon = (N-2)*180 N is no.of sides of polygon.

N*162=(N-2)*180.

N/(N-2) =10/9

N= 20
