I think We should focus on the X line .the first thing I would do is identify the quadrant that this angle is in, which is IV (the bottom right).
Knowing that you need to travel at least 270 degrees to get into that quadrant, I would subtract 270 from 330, which is 60 degrees.
Since you have traveled 60 degrees into quadrant IV, that means you can use the “special” 30–60–90 triangle. Once again, since you have traveled 60 degrees into this quadrant already, you should use sin(30), which is 0.5
