What is the angle sum of a regular polygon with 7 sides

sum of interior angles of a regular n-gon

= 180(n-2)

so sum = 180(5) = 900°

To find the angle sum of a regular polygon with n sides, you can use the formula:

Angle sum = (n - 2) * 180 degrees

In this case, we have a regular polygon with 7 sides, so we can substitute n = 7 into the formula:

Angle sum = (7 - 2) * 180 degrees
= 5 * 180 degrees
= 900 degrees

Therefore, the angle sum of a regular polygon with 7 sides is 900 degrees.
