Weight W = mg = 74 * 9.8 = 725.2 N
Horizontal Component of Tension T1 Cos theta1 = T2 cos theta2
Veritcal component T1 sin theta1 + T2 sin theta2 = W = 725.2 N
T1 cos 35 = T2 cos 48
T1/T2 = -0.816
T1 = 0.816 T2
so
0.816 T2 sin 35 + T2 sin 48 = 725.2
T2 = 598.75 N ---------------<<<<<<<<<<<<<<<<Answer to part B
T1 = 0.816 * 598.75
T1 = 489.1 N --------------<<<<<<<<<<<<<<<Answer to part A
