Question

What is the sum of the interior angles of the polygon pictured below?

Answer 1

Solution :-

We have

Side of polygon = 9

So,

By using the formula

(n - 2) × 180

(9 - 2) × 180

7 × 180

1260⁰

`\\`

Answer 2

The shape has 9 sides.

Sum of interior angles = (n-2) x 180, where n is the number of sides.

Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
