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

900°

1620°

1440°

1260°

D) 1260°

Step-by-step explanation:

Total angle: (n - 2) × 180

Nonagon has 9 sides, so n = 9

(9 - 2) × 180 = 1260

1260°

Step-by-step explanation:

Formula for this question:

(n - 2) × 180

n is the number of sides.

In a nonagon, there are 9 sides (nona).

So,

((9 - 2) × 180)

(7 × 180)

1260
