In the figure below the left-hand cable has a tension T1 and makes an angle of 50 with the horizontal. The right-hand cable has a tension T3 and makes an angle of θ3 with the horizontal. A 101 N weight is on the left and a 85 N weight is on the right. The cable connecting the two weights is horizontal.
a) Find the tension T1. Answer in units of N.
b) Find the tension T2. Answer in units of N.
c) Find the angle θ3. Answer in units of °.
