Question

If the coordinates (E, N, H) of points (A) and (H) were: A(300, 65, 152, 40, 53. 62) m and b(224.50, 88.95, 40.80.) m calculate: The azimuth of AB The vertical angle from (A) to (B) and determine its type (elevation or depression). To determine the height of a tower, a total station was placed at point (A) and the prism was placed at point (B) at the bottom of the tower. The mean distance was 60.85 m and the vertical angle was elevation angle = 4*30*25^-. The total station was top of the tower and the vertical angle was elevation angle -60*45*22*. The total station height was 1.55 m and the prism height was 1.70 m. Calculate the height was of the tower above ground. If the reduced level of point (A) is 15.40m calculate the reduced level of point (B).​
