Let \(A_1, A_2, A_3, ..., A_{15}\) be a regular polygon. A rotation centered at \(A_1\) with an angle of \(\alpha\) takes \(A_8\) to \(A_{15}\). Given that \(\alpha < 180^{\circ}\), find \(\alpha\) in degrees
Nevermind, I got the answer, it's 84
Basically you find the central angle which is 360/15. Then you do (15-8)*24, which equals 7*24 = 168. Finally you divide by 2 which gives you 84.
