Abuilding that is 245 feet tall casts a shadow of various lengths x as the day goes by. an angle of elevation θ is formed by lines from the top and bottom of the building to the tip of the shadow. 245 ftθx find the rate of change (in radians per foot) of the angle of elevation dθ dx when x = 300 feet. (round your answer to five decimal places.)
