Question

What is the sum of interior angles of a 22-gon?

3900

3600

4600

3960

I think 3600 looked and there is not a 100% yes or no about this answer 😭

Answer 1

Yes, correct.
While using the formula: S = (n-2) times 180 degrees, where 'n' is the number of sides. For a 22-gon, you substitute 'n' with 22 in the formula, so it should look like this : (22 - 2) times 180 = 20 times 180 = 3,600 degrees.
