Question

Find the number of sides of a regular polygon whose each exterior angle has a measure 45`

Answer 1

each exterior angle formula=360/n

45=360/n

n=360/45

n=18

Answer 2

Answer

Total measurement of all exterior angles is equal to 360 degree

Measure of each exterior angle is equal to 45 degree

(thereforethenumberofexteriorangle)=

45/360 =8

The polygon has 8 sides
