Drawing, or sketching the problem is always beneficial...
I took the liberty of doing it for you;
O-is the origin in this case... try figuring it out now, it should run along more smoothly...

Thanks a lot! But I can not understand a question. What should I find? Components of vector A? Or?
 
Yes, you need to express A using what you've been given, i.e r, r1, r2, xr...
Keep trying,
Daniel
