Can you help walk me through it? I have no idea what to do.

I made a video which covers this. If you understand similar triangles, then this becomes an easy problem. :) https://www.youtube.com/watch?v=wFmetfmpwXM&list=PL9FE48FF0B7A3E3F4&index=2 At 3:18 you can see the ratios of the sides of any given 30 60 90 triangle. Hope this helps.
