To find the sum of the interior angles of a nonagon (a 9-sided polygon), you can use the formula:

\[ \text{Sum of interior angles} = (n - 2) \times 180° \]

where \(n\) is the number of sides.

For a nonagon, \(n = 9\):

\[ \text{Sum of interior angles} = (9 - 2) \times 180° = 7 \times 180° = 1260° \]

Thus, the sum of the interior angles of a nonagon is 1,260 degrees.
