The slope distance and zenith angle between points A and B were measured with a total station instrument as 17685.20 ft and 93° 73’ 83", respectively. The height of instrument is found out to be 5.348 ft having rod reading 8.946 ft.
1. If the elevation of A is 1854.32 ft, compute the elevation of B.

On a average work day more than work place firs are reorted
