Question

How do you find the sum of the interior angles of a heptagon. Plz help!

Answer 1

Hey there!

The equation for finding the sum of the interior angles for a polygon with n sides is the following:


`180(n-2)`

"Hepta-" means seven; thus, a heptagon has 7 sides.

Since a heptagon has 7 sides, n=7.

Now, let's plug in that value into the equation.


`180(7-2)`


`=180(5)`


`=900`

Thus, the sum of all interior angles in a heptagon is 900 degrees.

Have an awesome day! :)
