    Pls help with number "B". The X component doesn't agree!

    Ignore the data entered in the fields for X,Y(incorrect). I later figured Y component is "-1", but have no idea why X didn't work out.

    Thx a lot!

    Yep; if you don't show us the reasoning we cannot help except to do the problem for you, and that would be against the rules.
