Hi, having a little trouble with this trig question. Keep getting tanx= 1/2 When x infact = 0, 30, 150, 360! Its probably something stupid i've missed, any help would be greatly appreciated!

Nice job factoring. Once you got to this stage: $\displaystyle csc(x) = 2$ $\displaystyle sec(x) = 1$ it is time to solve for your x values. For which degrees is $\displaystyle csc(x) = 2$ ? Also, for which degrees is $\displaystyle sec(x) = 1$ ?
Ah, I see, so then you solve those getting you your answers of 0, 360, 30, and 150. Great! So why is my way wrong? Because I can't see how its mathematically incorrect. It clearly is though.
Your method involved trying to get one x value from two equations with their own distinct x-values. You set up an equality that assumed that both the x values were the same, which is not correct.
I see, I thought as they were in the same equation they were the same. But now I see you solve it like a quadratic! Cheers, that's really helped alot!
