Explanation / Answer

in Y - direction the left and right cables

we can write equation as follows

L sin60 + R sin30 = 180.4

L X 0.866 + 0.5 X R = 180.4 ---------- 1

sameway in X - direction

L cos 60 = R cos 3 0

L = 1.732 R

above value substituted in equation 1

(1.732 R) X 0.866 + 0.5 X R = 180.4

1.4999 R = 180.4

R = 120.27 N

already we have

L = 1.732 R

L = 1.732 X 120.27

L = 208.31 N

so

Left cable tension is L = 208.31 N

Right cable tension is R = 120.27 N

Bottom cable tension is = 180.4 N
