Question

Find the number of sides of the regular polygon when the measure of an exterior angle is given.
1. 30°
2. 10°

Answer 1

We know that exterior angle of a regular polygon 360/no. of sides
1)Therefore no. of sides  = 360/30                                  
                                     =  12 sides 
2) Number of sides  = 360/10
                             =36 sides
Hope this helps :)
