Finding value of Force?

A uniform strut (i.e. a beam! I like to use fancy words!) of 130 kg is fixed on the ground by a hinge. The cable is attached at the other end and a 225 kg mass is also attached at the end.

I found the tension at 7772.4N and the horizontal component of the force exerted by the hinge on the strut at

6731.1 N. I can't find the vertical component of the force exerted by the hinge on the strut. I thought that because the angle is at 45deg, it would be the same as the x-component, but I got the answer wrong.

What am I doing wrong?
