Question

if the sum of interior angle in a polygon is 720degree,then find the no. of sides and name the polygon​

Answer 1

if the sum of interior angle in a polygon is 720degree.

A regular polygon consit of 9 sides,

9x=720

x=720/9

x=80

Answer 2

Answer:sum of total interior angle of polygon = (n - 2)180

so,(n-2)180=720

(n-2)=4

n=6

Therefore number of sides of polygon is six.

Hence,it is hexagon
