I believe this is a static equilibrium question but cant figure out how to do it

The net force on the x-axis must be zero. What equation can you make from this fact?

Also the net torque is zero. Take the torques around the A point. What equation can you make?

Solving these two equations with two unknowns (F_x and the force from cable ) will get you the result.

•  this is what i have split the forces as till now,
somehow i cant get them to cancel

You get involved with the forces along the line of the 80Kg rod, that's not what you should do, the x-axis is not the line of the 80Kg rod, the first picture at OP shows which are the x -axis and the y-axis.

In the y-axis you got the weights of the rod and the mass m, 80Kg and 10Kg respectively (and the F_y component of the force from wall at A).
In the x-axis you got F_x and the tension T from the cable.

ah got it thank you
