Question

plzz answer for this​

Answer 1

Step-by-step explanation:

(n-2)×180°=So a triangle has three sides.

(3-2)×180°=Sum of interior angles=180°

So if:(n-2)×180°=1600°

(n-2)=1600/180

(n-2)=8.89

n=8.89+2=10.89

It cannot be in decimals so sum cannot be 1600°.

(n-2)=900/180

n=5+2=7

7 sides are possible so sum of angles can be 900.7-sided figure is called:Heptagon.
