A weight W is supported by two strings inclined at 60° and 30° to the vertical. The tensions in the strings are ${\mathrm{T}}_1$ and ${\text{T}}_2$, as shown. If these tensions are to be determined in terms of W using a triangle of forces, which of these triangles should you draw? (block is in equilibrium)
