The tension in rope A is 740.88 N, the tension carried by rope B is 751.4 N and the tension carried by rope C is -124 N.

Angle made by B with respect to horizontal

tan θ = Δy/Δx

tan θ = (10 - 4)/(5 - 4)

tan θ = 6

θ = arc tan (6) = 80.53

Net force in vertical direction

C sin(0) + B sin(80.53)  = A sin(90)

C sin(0) + B sin(80.53)  = (75.6 x 9.8)

0 + 0.986 B = 740.88

0.986 B = 740.88

B = 740.88/0.986

B = 751.4 N

Net force in horizontal direction

C cos(0) + B cos(80.53) = (75.6 x 9.8) cos(90)

C + 0.165 B = 0

C + 0.165(751.4) = 0

C + 124 = 0

C = - 124 N

Thus, the tension in rope A is 740.88 N, the tension carried by rope B is 751.4 N and the tension carried by rope C is -124 N.
