2. Vector A = Ax + Ay
Ax = magnitude X xi
Ay = magnitude X yi

3. I don't know how to start.
 
any way to provide the diagram?

Try starting by figuring out how long A is, and in what direction it points.

That's very confused :redface: …

you mean A = Ax x i + Ay x j.

ok, so in this case Ax = … ? :smile:
