Tension in cable CD is T1 = 30*9.8 = 294 N
now tension in cable AC is T2 and in cable BC is T3
now Horizontal balance
T2*cos(45 degrees) + T3*cos(60 degrees) = T1*cos(15 dgerees)
=> 0.707*T2 + 0.5*T3 = 294*0.965 = 283.71 ........eq1
and vertical balance
T2sin(45 degrees)+ T1sin(15 degrees) = T3sin(60degrees)
=> 0.707*T2 + 0.258*T1 = 0.866*T3
=> 0.707*T2 + 75.852 = 0.866*T3......eq2
from both equations
283.71 - 0.5*T3 + 75.852 = 0.866*T3
=> T3 = 263.22 N Tension in BC
=> T2 = 283.71 - 0.5*T3 = 152.1 N Tension in AC
