1260 degrees
is the correct answer. By plugging 9 into 180(n-2), we get 1260.

Use the formula to find the sum of the measures of interior angles of a polygon: (n - 2) × 180, where n is the number of sides.
A nonagon has 9 sides, so plug in 9 for n.
(9 - 2) × 180
7 × 180 = 1,260
A nonagon's interior angles add up to
1,260°.
