The system in the image below is at equilibrium. The smooth rod has a mass of 8.00 kg, and a centre of mass at point G, which is halfway along the length of the rod. You can neglect the mass of the rope, which attaches to a hook on the wall. Determine the distance along the wall between the hook and the rod. (g = 9.81m/s^2)

Here is some trigonometry information that may help you (note: you do not have to use this):

sin(180 - theta) = sin(theta)

Cosine law: a^2 = b^2 + c^2 -2bc*cos(alpha)
