From the diagram above, solve for the reaction at point A. and the tension in the cable that is attatched at point C. Assume the bar is mass-less. Block B has a mass of 124 kg. The distance from point B to point A is 3.2m, from point A to point D is 1.3 m, and point D to point C 2.1 m. The cable attaches to the wall forming a 30 degree angle with the wall.

This is an equation with an attached pic from my highschool physics class. It was a "just for fun" problem that the teacher does not expect us to be able to figure out, but I wanted to know if someone could give me some suggestions, I really have no idea. This is not for a grade, other wise I would have attempted it in a more vigourous level.
