Which is the formula for finding the sum of the interior angles of a polygon?

180(n + 2) where n is the number of sides
180(n – 2) where n is the number of sides
360(n + 2) where n is the number of sides
360(n – 2) where n is the number of sides

The number of sides would be 180(n-2), we can test this theory with a triangle (interior angles add up to 180). A triangle has 3 sides so:

180(1) = 180

Therefore, the aforementioned equation is valid!

It would be
180(n – 2) where n is the number of sides
