The drawing shows a wire tooth brace used by orthodontists. The top-most tooth is protruding slightly, and the tension in the wire exerts two forces, and T,T1 on this tooth in order to bring it back into alignment. If the forces have the same magnitude of 20.7 N, what is the magnitude of the net force exerted on the tooth by these forces?

Without the drawing I have no idea of directions of these force vectors. I do not do magic :)
