Labelling the tensions:
The net tension in the x-axis will be:
ΣTx = T1 sin θ - T2 sinθ
Along the y-axis
ΣTy = T1 cosθ + T2 cos θ
But ΣTy = 5.00N
Due to a jaw injury, a patient must wear a strap (see the figure) that produces a net upward force of 5.00N on his chin. The tension is the same throughout the strap.
To what tension must the strap be adjusted to provide the necessary upward force?
