**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.

**2. Relevant equations**

net torque = 0

**3. The attempt at a solution**

this is how i did it, the answer was wrong 🙁
