Answer 2

Answer:

no. of sides can be 9 or 16

Step-by-step explanation:

smallest angle=120*

c.d=5*

Ap is 120, 125, 130,............

the sum of interior angles of a polygon =(n-2)180

hence, sum of n terms of an ap=(n-2)180

n/2 {2.120+(n-1)5}=180 (n-2)

5n^2-125n+720=0

n^2-25n+144=0

☆n=9 or 16 ⭐⭐

hope it helps........have a good day....
