Step-by-step explanation:

formula for finding sum of interior angle =(n-2)×180

(a)1620

(n-2)×180=1620

n-2=1620÷180

n-2=9

n=11

no of sides is 11

(b)2160

(n-2)×180=2160

(n-2)=2160÷180

(n-2)=12

n=12+2

n=14

no of sides is 14

(c)2700

(n-2)×180=2700

(n-2)=2700÷180

n-2=15

n=17 no of sides is 17
