**1. The problem statement, all variables and given/known data**

A nonuniform, horizontal bar of mass m is supported by two massless wires against gravity. The left wire makes an angle ϕ1 with the horizontal, and the right wire makes an angle ϕ2. The bar has length L.

Find the position of the center of mass of the bar, x, measured from the bar's left end.

**2. Relevant equations**

net torque = 0

**3. The attempt at a solution**

this is how i did it, the answer was wrong :(

and all answers i found online was L/((tanø2/tanø1)+1) which is incorrect.

help please, thank you very much
