A floodlight with a mass of (19,0 Kg) is supported at the end of a horizontal beam that's hinged to a vertical pole, as shown. A cable that makes an angle of (27 degrees) with the beam is attached to the pole to help support the floodlight. Assume the mass of the beam is negligible when compared with the mass of the floodlight. Find Tension provided by the cable. (Answer in N). Find the horizontal force exerted on the beam by the pole? Find the Vertical Force exerted on the beam by the pole.

Relevant equations
F = ma = 0
T = I (alpha) = 0
Here's what I tried doing, I set the x,y components of F to 0 to find a T from the normal force, gravity and the beam, set them all to 0.
F = -Tsin(63){x-direction} + Tcos(63){y-direction} = 0, and I tried solving for T? I then realized that like this is if there was a pin in the beam, and the beam had mass, so that can't be correct.
I'm just asking for some direction with some values...? HELP?
