Question

3. What is the number of sides of a regular polygon with the sum of angles as:
(1) 1620°
(ii) 2520°
(iii) 3240°​

Answer 1

Answer:

Sum of angles of a regular polygon with 'n' sides is given by the formula (n - 2)x180

therefore

(n - 2)x180=1620

=>n - 2=1620/180

therefore n =11

the number of sides of a regular polygon with the sum of angles as : 1620°=11 sides.

for 2520°

(n-2)x180=2520

n-2=2520/180

n=21

the number of sides of a regular polygon with the sum of angles as :2520°=21
