I've got some online Physics homework on Vectors, and I'm stuck on a particular question:
"A trolley has a weight of 11N and sits on a ramp inclined at 33° to the horizontal. How big is the component of the weight which is trying to pull the trolley along the ramp? Give your answer to 2 significant figures."
Who knew A-level Physics was so hard? I have no idea what to do.
Can someone please help me? I've gotta finish it today. (BTW sorry if I posted it in the wrong place, can the admins move it if it is?)

I tried imagining it as a right-angled triangle (with the right bottom angle as 33°). Then, I tried making the hypotenuse 11N and using SOH CAH TOA to calculate the other sides, then trying each value inside the answer box. It said it was incorrect each time, so I tried making 11N the opposite to 33° instead, and then the adjacent to 33°, then recalculating all the values each time. I still can't get a correct answer. I give up.
