You are in a group of 3 surveyors (you and two other people). Your group has two range poles, one at 12 feet high and one at 17 feet high. The ground you are surveying is considered to be level. You stand in a spot with the angle measuring tool (a theodolite). Each partner carries one of the poles. You space everyone out until the following occurs. The angle created between you and the two poles horizontally is 90°. The angle of elevation between you and the top of the 12-foot pole is 14.5°. The angle of elevation between you and the 17-foot pole is 19.4°. How far apart are the two other people, holding the 12 and 17-foot poles?
