Answer 15

And each time you go around another quarter turn, it adds another three. If you go the opposite direction, it subtracts three. So if I went clockwise twice more, the upper axis is \(15\pi / 6\) too, or I could say the bottom axis is \(-3\pi /6\). Those sorts of rules are important for answering these questions.

I did the axis, but you need the drawn lines. So just find out what the possible measures on the drawn lines are and you are there.
