Extracted text: The depth of a fishing lure being pulled through the water can be determined by the angle of depression where the line enters the water and the length of line that is let out from the surface of the water. Mr. Vaerst let out 80 feet of line forming a 30° angle of depression with the surface of the water. Determine the depth of his lure to the nearest tenth of a foot.
