A boat sails directly toward a 300-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 gure). Complete pans a and b below. 3. Use a trigonometric equation to nd an expression for the angle, 0, in terms of x. (Type an equation.) d9 What is the rate of change of the angular size, a, when the boat is x = 500 m from the building? rad/m (Round to ve decimal places as needed.) d6 b. Graph 3 as a function of x and determine the point at which the angular size changes most rapidly. Choose the correct graph below. O A- O B. , . Q q . / (ii/7; [0,1000] by [0,0005] [0,1000] by [0.00520] For Miat value of x is the angular size changing most rapidly? x= (Round to the nearest integer as needed.) [0,1000] by [0.0.005] 7 :1? [0,1000] by [ 0005.0]
