Question

1. Finding the Width of a River A surveyor can measure the width of a river by setting up a transit at a point C on one side of the river and taking a sighting of a point A on the other side. Refer to Figure 33. After turning through an angle of 90 at C, the surveyor walks a distance of 200 meters to point B. Using the transit at B, the angle ? is measured and found to be 20 . What is the width of the river rounded to the nearest meter? 2. Finding the Height of a Statue on a Building Adorning the top of the Board of Trade building in Chicago is a statue of Ceres, the Roman goddess of wheat. From street level, two observations are taken 400 feet from the center of the building. The angle of elevation to the base of the statue is found to be 55.1 , and the angle of elevation to the top of the statue is 56.5 . See Figure 36(a). What is the height of the statue?
