Answer:
<h2><u>Solution</u><u> </u><u>:</u><u>-</u></h2>
We have
Side of polygon = 9
So,
By using the formula
(n - 2) × 180
(9 - 2) × 180
7 × 180
1260⁰
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.
