PLEASE HELP I REALLY DONT KNKW HOW TO DO THIS- To measure the width of the Grand Canyon, a surveyor stands at a point on the North Rim of the canyon and measures the angle of depression to a point directly across on the South Rim of the canyon. The angle of depression is 19 degrees. At the surveyor's position on the North Rim, the Grand Canyon is 7,256 feet above sea level. The point on the South Rim, directly across, is 6,159 feet above sea level. Sketch a diagram of the situation and determine the width of the Grand Canyon at the surveyor's position.
