A boat sails directly toward a 250-m skyscraper that stands on the edge of a harbor. The angular size of the building is the angle formed by lines from the top and bottom of the building to the observer (see figure). Complete parts a and b below. 250 m a. Use a trigonometric equation to find an expression for the angle, 0, in terms of | (Type an equation.) de when the boat is x= 400 m from the dx What is the rate of change of the angular size, building? rad/m (Round to five decimal places as needed.) de b. Graph y as a function of x and determine the point at which the angular size changes most rapidly. Choose the correct graph below. O A. В.
