To find the sum of angles in a nonagon, we need to know the number of sides it has and use a formula.
A nonagon is a polygon with nine sides.
The formula to calculate the sum of angles in any polygon is:
Sum of Angles = (n - 2) * 180 degrees
Where "n" is the number of sides of the polygon.
For a nonagon, plugging in the value of "n" as 9:
Sum of Angles = (9 - 2) * 180 degrees
= 7 * 180 degrees
= 1260 degrees
So, the sum of angles in a nonagon is 1260 degrees.
