The sum of the interior angles of a polygon can be found using the formula (n-2) * 180, where n is the number of sides of the polygon.
Therefore, for a 22-gon, the sum of the interior angles would be (22-2) * 180 = 20 * 180 = 3600°.
So the correct answer is 3600°.

Saying why again
an exterior angle is 180 + 360 / n
so an interior angle is 360 - (180 +360/n) = 180 - 360/n
sum of interiors = n (180-360/n) = 180 n - 360 = 180 ( n - 2)
an exterior angle is 180 + 360 / n
so an interior angle is 360 - (180 +360/n) = 180 - 360/n
sum of interiors = n (180-360/n) = 180 n - 360 = 180 ( n - 2)
I apologize for the confusion. You are correct. The sum of the interior angles of a polygon is given by the formula (n-2) * 180, where n is the number of sides of the polygon.
For a 22-gon, the sum of the interior angles would be (22-2) * 180 = 20 * 180 = 3600°.
Therefore, the correct answer is indeed 3600°.
