What is the Height of Instrument (HI) in engineering feet if using an EDM you take a BS over a BM with a known elevation of 95.70' AMSL, and you see the following sight on the level rod? (enter only a numerical answer).

The height of an EDM set up at M is 1.495 m. The height of a reflector set up at P is 1.30 m. The height of the theodolite at M used to measure the vertical angle is 1.615 m. The height of the target at P on which the vertical sight is taken is 1.385 m. the slope distance after meteorological corrections is 1650.452 m. The measured vertical angle is +3°02'32". What is the horizontal distance between M and P. (

The height of an EDM set up at station A is 1.415 m. The height of the reflector set up at station B is 1.124 m. The height of the theodolite at station A used to measure the vertical angle is 1.623 m. The height of the target at station B on which the vertical angle sight is taken is 1.175 m. The measured vertical angle is 5° 32' 45" (upward). The slope distance, after meteorological corrections, is 1537.248 m. Determine the horizontal distance between stations A and B.

An EDM slope distance AB is determined to be 561.276 m. The EDM instrument is 1.820 mabove station A, and the prism is 1.986 m above station B. The EDM instrument is mounted ona theodolite whose optical center is 1.720 m above the station. The theodolite was used tomeasure the vertical angle (+6°21’38’’) to a target on the prism pole; the target is 1.810 mabove station B. With help of a diagram compute both the horizontal distance AB and theelevation of Station B, if the elevation of station A=186.275

A slope distance of 165.360 m (corrected for meteorological conditions) was measured from A to B, whose elevations were 447.401 and 445.389 m above datum, respectively. Find the horizontal length of line AB if the heights of the EDM instrument and reflector were 1.417 and 1.615 m above their respective stations. (

A slope distance of 204.834 m was determined by EDM, the instrument and prism having been set up 1.645 m and 1.873 m respectively above their stations. The vertical angle between the stations was later measured as 2° 17' 40", the instrument station being the higher of the two. Calculate the horizontal length of the line.
