Question

(3) Is the sum of the angles of any polygon 1600°? How about 900°?​

Answer 1

Answer:

The sum the angles of any polygon is (n-2)*180°

Where n is no of vertices.

1600=(n-2)*180

1600/180=(n-1)

80/9=(n-1)

n=80/9+1

n=89/1

THEREFORE IT IS NOT POSSIBLE.

900=(n-2)*180

900/180=n-2

5=n-2

n=7

THEREFORE IT IS POSSIBLE.
