A block is L = 1 [m] long and h = 0.5 [m] tall and weighs 50 [N]. The box is allowed to rotate about point A. A rope is attached to the upper left corner. This rope makes a θ=40° angle from the horizon. A horizontal force of 30 [N] is applied at the lower left corner. Find the magnitude of the reactions at A and the tension in the rope. Input your answer in Newtons to two decimal places.
