A bag of cement of weight 370 N hangs from three wires
Two of the wires make angles è1 = 58.6° and è2 = 23.8° with the horizontal. If the system is in equilibrium, calculate the tension T1.

bobpursley,
You know the sum of forces is zero, in the vertical and horizontal.
In the horizontal
0=T1cos58.6 + T2cos23.8
In the vertical
370=T1sin58.6 + ....
From this, you get two equations, two unknowns.
