Please assist with this question with details on how to do it. Thank you. A bag of cement weighing 325 N hangs in equilibrium from three wires as suggested in Figures P4.23. Two of the wires make angles Theta1 = 60 degrees and theta2 = 40 degrees with the horizontal. Assuming the system is in equilibrium, find the tensions t1, t2, and t3 in the wires. .
