Answer 2

Answer:

i. 12

ii. 8

Step-by-step explanation:

I. as it is a regular polygon all exterior angles are = 360 degree

measure of exterior angle = 30 degree

let no. of sides =n

so, 360/n=30

360/30=12

hence, no. of sides of a regular polygon are 12.

ii. total measure of exterior angles = 360 degree

measure of exterior angle = 45 degree

let no. of sides = n

so, 360/n = 45

360/45=n

8=n

hence , no. of sides of a regular polygon are 8.
