Components of a Vector

Hi --

I'm working on a physics problem that involves adding several vectors. I know that to find the components of a vector you must do some trig with the angle the vector makes with the x-axis. However, one of the vectors is parallel to the x-axis (but not actually laying ON the x-axis). I'm not sure where to go from there; how to find its components. I tried a few things, but none of them seem to give me the correct answer.

Can anyone help me out with this?

The vector will simply have an x component and no y component.
Hmm, ok. Will the x component just be the length of the vector then?
Yes, you're right.
