Unformatted text preview: 5.3 degrres 5. From a point on the North Rim of the Grand Canyon, a surveyor measures an angle of depression of 1 o 02’. The horizontal distance between the two points is estimated to be 11 miles. How many feet is the South Rim below the North Rim? 1048 feet 6. In one minute a plane descending at a constant angle of depression of 12 o 24’ travels 1600 meters along its line of flight. How much altitude has it lost? 343.6 meters Writing activity: Compare an angle of elevation to an angle of depression. Possible answer should include the fact that both angles are made with the horizontal. The angle of elevation is the angle between the horizontal and the line of sight when looking up at the object. The angle of depression is the angle between the horizontal and the line of sight when looking down on an object....
