Homework Help: Vectors Diagram Question

  1. Oct 6, 2011 #1
    Hey everyone! :)

    1. The problem statement, all variables and given/known data
    Okay. Here's a snapshot of the question (I'm only interested in parts b) i) and ii) ):

    2. The attempt at a solution
    I know the answer, and I got it too. But I have a feeling that I'm doing too much. Below are snapshots of my attempt (please let me know if you can not understand something). Is there a simpler way to do this? Also, how should I do it by the drawing method?

    Thanks in advance. :-)
    [PS: Sorry about the pictures. I couldn't figure out how to put them right. :( ]
