Answer 1

Answer:

1980° and 1620°.

Step-by-step explanation:

Let the number of sides of the polygon be n.

Then, (n-2)×180=1800

=>n-2=1800/180

=>n-2=10

=>n=10+2

=>n=12.

Therefore, number of sides of the polygon is 12.

(i) Sum of the angles of the polygon with one side more=(12+1-2)×180°

=11×180°

=1980°.

(ii) Sum of the angles of the polygon with one side less=(12-1-2)×180°

=9×180°

=1620°.
