The top of tower at Point B is viewed at point A using an instrument with height of 150 cm above point A. Point A has an elevation of 20 m above sea level. a) What is the elevation of the top of tower at point B if it is 25 km away from the point A? b) How far is point A in meters if the top of the tower at point B is 15.945 m above sea level? c) What is the elevation of the tower at a distance 25 km away from the point A that will just be visible without the line of sight approaching nearer than 21.50 m to the water?
