In a vertical photograph, a tower appears at a distance of 60 mm from the principle point. The focal length of the camera used is 200 mm. The elevation of the bottom of the tower is 1000 m. The displacement of the top of the tower with respect to the image of its bottom measures (6+K) mm, where K = 85/100. If for a flat area, a line of length 500 m on ground measures 100 mm in the photograph, calculate and write the elevation of top of the tower.
