Hi,
Let T1 be the tension of the line at 53 degrees and T2 be the other line connected to the side wall.
ΣFx = T1 Cos 53 – T2 Cos 0 = 0 …. (Eq 1)
ΣFy = T1 Sin 53 +T2 Sin 0 -74=0…. (Eq2)
T1 Sin 53 +0 = 74…. (From Eq 2)
.6018T1 =74
T1 = 122.96
T1Cos53 =T2 Cos 0 (from Eq 1)
T1 Cos 53 = T2
122.96 (.6018) = T2
T2 = 74
