Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon
[tex]Sum\ of\ interior\ angles = (n-2)*180[/tex]
Here n is the number of sides of polygon
In the given polygon
n = 7
So,
[tex]Sum = (7-2)*180 = 5*180 = 900[/tex]
Hence,
The sum of interior angles of given polygon is 900°
