You can use these two equation: \[y=y_0 +v_0\sin{\alpha}-\frac12 g t^2\] and \[x=v_0 \cos{\alpha}*t\] That's all you need
Can I use either equation to get the answer or do I have to use both somehow?
You have to use both, you might like to find t from second equation first, then substitute to first equation.

Ok, I got an answer for t, but I don't understand why I need to plug in that figure to the first equation since I've already found time.
Good, of course you don't need to. This problem's just overresource. Sorry for my previous answer, i'm not concentrating back then :)
Lol.. that's ok. :) Thanks for your help!
