Question

How many sides does a regular polygon have if each of its interior angles is 165 drgèr

Answer 1

Answer:

since the measure of each interior angle is 165 degree , we have

180 degree(n-2)/n = 165 degree

180 degree(n-2) = 165 degree×n

180degree ×n - 360 degree = 165 degree×n

180 degree ×n - 165 degree×n = 360 degree

15 degree ×n = 360 degree

n=24
