Question

What is the sum of the interior angles of a nonagon?

Answer 1

The formula is (n-2)180

Answer 2

Number of sides in a nonagon is 9.
The formula for the sum of the interior angles of a polygon is:
180(n-2), where n is the number of sides.

180(9-2)

180*7

1260°

Answer 3

N stands for the number of sides, there are 9 sides

Answer 4

Sum of interior angles of a polygon = (n-2) × 180°

in this equation, substitute n with 9, to get the sum for a nonagon.
