Question

Find the number of sides of a regular polygon if each of its interior angle is 168°

Answer 1

simply plug in the formula

Answer 2

Answer:30 degre

Step-by-step explanation:

Let the no. of side be x ,

Exterior angle = 180 degree - 168 degree= 12 degree

Sum of exterior angles of a regular polygon =360 degree

Number of sides = sum of exterior angles divided by each interior angle= 360 degree divided by 12 degree = 30 degree
