Answer:
So, n= 18; i.e the polygon has 18 sides and their sum of interior angles is 2880
Explanation:
In this question we have been given the sum of interior angles of a polygon which is 2880, having n sides. We have to find n i.e the no of sides of polygon.
The formula used is S= (n-2) *180
where S= sum of interior angles
and n= no of sides
putting value of S and finding n,
2880 = (n-2) *180
2880/180 = (n-2)
16 = n-2
=> n= 16 +2
=> n= 18
So, n= 18; i.e the polygon has 18 sides and their sum of interior angles is 2880
