A guy-wire supports a pole that is 85 ft high. One end of the wire is attached to the top of the pole and the other end is anchored to the ground 50 ft from the base of the pole. Determine the horizontal and vertical components (in lb) of the force of tension in the wire if its magnitude is 50 lb. (Round your answers to the nearest integer.)
