Question

find the number of side of regular polygon whose each exterior angle has measure 45​

Answer 1

sum of all exterior angle of polygon is 360 degree.
then the side of polygon is 360/45=8
hence number of side=8.
hope it help you.

Answer 2

Answer:

Step-by-step explanation:

exterior angle=45

sum of exterior angles of a regular polygon = 360

let no.of side of regular polygon be N

now measure of each exterior angle = $\frac{360}{N}$

45=360/N

N=8

SO, NO.SIDES ARE 8
