    start by writing the tensions in vertical and horizontal components so that you will have 2 equations to solve simultaneously. remember that the weight is horizontal

    So I would have T1 as <cos(50),sin(50)> and T2 as <cos(30),sin(30)>? Or do I have to subtract 50 from 180 for T1? Thanks for your help.

    you use 90 degrees there is no need to use 180

    So T1 = <153.2,128.6> and \[T_2 = <100,100\sqrt3>\] Can I just put that into ai+bj format?

    as long as you show that you have T1 and T2 answers
