  1. Bottom cable first :) 165.8 N

    handy 30+60 = 90 :)
    draw vertical line through the point where three cables meet
    then vertical problem:
    Tleft cos 30 + Tright cos 60 = 168 (net = weight)
    and horizontal problem (net = 0)
    Tleft cos 60 = Tright cos 30
    solve for Tleft and Tright
