Answer 1

Finding the Interior Angles of a Regular Polygon with n=9

To find the interior angles of a regular polygon with n=9, we can use the formula:

Interior Angle = (n-2) * 180° / n

Substitute n=9 into the formula to find the interior angle of the regular 9-sided polygon.

Interior Angle = (9-2) * 180° / 9

Interior Angle = 7 * 180° / 9

Interior Angle = 1260° / 9

Interior Angle = 140°

Therefore, the interior angle of a regular 9-sided polygon (nonagon) is 140 degrees. This calculation is based on the formula for finding the interior angles of a regular polygon.

This information is based on the formula for calculating the interior angles of regular polygons and is widely used in geometry and mathematics
