Question

If an exterior angle of a regular polygon is 45°, then find the number of its sides

Answer 1

Answer:

8 sides

Step-by-step explanation:

sum of exterior angles = 360 degrees

no of sides(n) = $\frac{sum of exterior angles of a regular polygon}{given exterior angle of the regular polygon}$

                       =$\frac{360}{45}$

                      ⇒8 sides.

Answer 2

Step-by-step explanation:

sum of exterior angle = 360

as each exterior angle of a polygon is 45, then the number of sides=360/45=8

8 sides..
