Challenge! Ready? An airplane pilot over the Pacific sights an atoll at an angle of depression of 7 degrees. At this time, the horizontal distance from the airplane to the atoll is 3,729 meters. What is the height of the plane to the nearest meter? http://assets.openstudy.com/updates/attachments/5383b347e4b05a9ada0c84ac-ashley137-1401140067213-941080719201335228pm816559023.gif
