Show the complete solution and the necessary graphs/diagrams. Use 2 decimal places in the final answer. As part of a department store display, a model train D runs on a slight incline between the store’s up and down escalators. When the train and shoppers pass point A, the train appears to the shopper on the up escalator B to move downward at an angle of 22° with the horizontal, and to a shopper on the down escalator C to move upward at an angle of 23° with the horizontal to travel to the left. Knowing that the speed of the escalators is 3 ft/s, determine the direction (in degrees) of the train. Indicate if it is "up to the right", "up to the left", "down to the right", or "down to the left", along with the angle of inclination from the horizontal.
