Resolving of vectors

  1. Apr 12, 2010 #1
    1. The problem statement, all variables and given/known data
    I have two equations in which I need to solve for T, involving two different variables and I'm not too sure how to solve.
    (G = 9.8)
    10 + T2cos25−T1cos45 = 0
    T1sin 45+ T2sin 25−8g = 0

    2. Relevant equations

    10 + T2cos25−T1cos45 = 0
    T1sin 45+ T2sin 25−8g = 0

    3. The attempt at a solution

    I tried solving where i used the values of cos 25/45 and sin 25/45 and I couldn't get anywhere.

    Hi olee! :smile:
    uhhh? multiply the first equation by sin25º, and the second equation by cos25º, and subtract, to get an equation in T1.
