4.8 Solving Problems with Trigonometry Name: _________________ Objectives: Students will be able to apply the concepts of trigonometry to solve real-world problems. Nov 151:00 PM The angle of depression of a buoy from the top of a lighthouse 130 feet above the surface of the water is 6o. Find the distance x from the base of the lighthouse to the buoy. Nov 151:18 PM 1 From the top of a 100 ft tall building a man observes a car moving toward the building. If the angle of depression of the car changes from 22o to 46o during the period of observation, how far does the car travel? Nov 151:37 PM To measure the height of a cloud, you place a bright searchlight directly below the cloud and shine the beam straight up. From a point 100 feet away from the searchlight, you measure the angle of elevation of the cloud to be 83o12'. How high is the cloud? Assignment: 1-7 odd, 16 Nov 152:28 PM 2 Nov 217:49 AM 3
