225 ft X A building that is 225 feet tall casts a shadow of various lengths as the day goes by. An angle of elevation O is formed by lines from the top and bottom of the building to the tip of the shadow, as seen in the figure above. de Find the rate of change of the angle of elevation -when I = 207. e' (207) = radians per foot. Round to five decimal places. 75 ft X A pole stands 75 feet tall. An angle O is formed when wires of various lengths of I feet are attached from the ground to the top of the pole, as shown in the following figure. do Find the rate of change of the angle when a wire of 154 feet is attached. 0' (154) = radians per foot. Round to five decimal places
