At equilibrium:
Note: the horizontal components are equal.
If three forces are in equilibrium the vector sum of all the forces is zero. If you draw a vector diagram and place the arrows tip to tail it would form a closed triangle. If the arrows are arranged tip to tail and the tip of the last vectors touches the tail of the first the forces are in equilibrium.
