What is the maximum value the angle theta can have if the stick is to remain in equilibrium?

Maybe someone could point me in the right direction. so far i've calculated the sum of torques (equal to zero for equilibrium) and i got xf=(1-x)Tsin(theta)

where f is friction and T is the tension in the cord. Also i know that f=(0.37)N. I have no idea what else I can use here. Please help! Thanks.
