# 1)a)What is the sum of angles of a hexagon? b)If the number of sides of a polygon increases one by one, what will be the increment in sum of inner angles.

Sum of angles=(n-2)180

(6-2)180

4?180=740?

One angle=740?6=120?

If the number of sides of apolygon increases one by one,the sum of inner angles will be increased to 180?
