Question

The sum of angles of a polygon is 10440º. Then

a) The sum of angles of a polygon with one more side

= 10440 +...... = .......

b) The sum of angles of a polygon with one side less

= 10440 - ...... = .......​

Answer 1

Answer:

a. polygon is of five sides

so let the sides of polygon be 5x

5x=10440

x=2088

so 10440+2088=12528

b. if we subtract a side from polygon it will be quadrilateral

so angle of one side is 2088

then, 10440-2088=8352
