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?
A vertical photograph of a flat area having an average elevation of 250 m above mean sea level was taken with a camera of focal length 25 cm. A section line AB 300 m appears 15 cm on the photograph. The distance b/w images of top and bottom of the tower measures 0.5 cm on the photograph. The distance of the image of the top of the tower is 10 cm. Find the actual height of the tower.

A backsight is taken on a benchmark of rod reading of 1.30 meters, vertical angle of 22° 30’, and slope distance distance from instrument of 57.6 m. A foresight is taken on a point A with rod reading of 0.80 m., vertical angle of 8° 15’, and a horizontal distance of 40.50 m from the instrument. If the height of instrument is 1.20 m. having a ground elevation of 537.98 m., determine the elevation BM and point A disregarding the effect of curvature and refraction.
