In trying to move across a slippery icy surface, a 165-lb man uses two ropes AB and AC. Knowing that the force exerted on the man by the icy surface is perpendicular to that surface, determine the tension in each rope, assuming that a friend is helping the man at A by pulling on him with a force P = (-35 lb)k.
