The sum of interior angles of the given polygon is 900 degrees
How to calculate the sum of an interior angle of a polygon?
The formula used to calculate the sum of an interior angle of a polygon is expressed as:
Sum of interior angles = ( n − 2 ) × 180 ∘
n is the number of sides
The number of sides of the given polygon is 7, hence;
Sum of interior angles = (7 − 2 ) × 180 ∘
Sum of interior angles = 5 × 180 ∘
Sum of interior angles = 900 degrees
Hence the sum of interior angles of the given polygon is 900 degrees
