A 11-kg storm window measuring 900×1500 mm is held by hinges at A and B. In the position shown, it is held away from the side of a house by a 600-mm stick CD. Assuming that the hinge at A does not exert any axial thrust, determine the magnitude of the force exerted by the stick and the components of the reactions at A and B. (Round the final answers to one decimal place.)
