Hey, I don't even know where to begin to solve this problem.

If sinx= -1/2 and cosx=radical3/2, find a possible measure for angle X between 0 and 2pi.

Would this problem have anything to do with a 30/60/90 triangle?

Thanks for any and all help

So after solving with the triangle, x would equal 30o right? So then is that the final answer, or would you subtract it from 360 making it 330o? I think I need one more clue on how to solve it. Sorry if this is an easy question, I've been really sick for the past few days and am not my usual self.
