A bag of cement whose weight is $F_g$ hangs in equilibrium from three
-wires shown in Figure P5.24. Two of the wires make angles
+wires shown in Figure~P5.24. Two of the wires make angles
$\theta_1=60.0\dg$ and $\theta_2=40.0\dg$ with the horizontal.
Assuming the system is in equilibrium, show that the tension in the
left-hand wire is
