Answer 2

22 is A

23 is A

24 is C

25 is B

Explanation:

for #22, the equation is 108n = [(n - 2) × 180 degrees]. making that 108n = 180n - 360, then move the 180n to the other side to make 108n - 180n = 360. making that 72n = 360. That makes n = 5.

For #23, the equation would be (n - 2) × 180, n = 7, 7-2 = 5 and then 5 × 180 = 900 degrees.

For #24 the equation is 360/n, n = 5, meaning 360/5 would equal 72 degrees.

For #25, the equation would be 360/n, n = 22.5, meaning 360/22.5 would equal to 16 sides for each exterior angle.
