You are given a vector in the xy plane that has a magnitude of 90.0 units and a y component of -55.0 units.

a) what are the two possibilities for its x component?

b) assuming the x component is known to be positive, specify the vector which, if you add it to the original one, would give a resultant vector that is 80.0 units long and points entirely in the -x direction.

I have no idea how to do this. I thought I did it correctly but now I'm not so sure.

if you could do this step by step that would be great. Don't get too high tech on me though because you will confuse me more and I won't get what you're saying. lol.

I saw someone with a similar problem but she got part a and I didn't.

thanks a ton. :tongue:
