A TES setup was used in the field to determine the height of the new building. The following measurements were taken:
Horizontal distance from the instrument to the building = 150
ft
Zenith angle from instrument to the top of the building =
42o 30’ 0’’
Elevation of nearby benchmark = 100.00 ft
Backsight from the instrument to benchmark = 3.4 ft

Using a total station, a vertical angle of +5 28'12" was taken to a target set 1.700 m above benchmark A of elevation 175.926 m. The EDM slope distance to a reflector set over benchmark A was 443.355 m. From the same setup, a vertical angle of +11°42'12" was then taken to a target set 1.300 m over a point B at the top of the hill and an EDM slope distance of 341.682 m was taken to a reflector...

In order to estimate the height of a building, two students stand at a certain distance from the building at street level. From this point, they find the angle of elevation from the street to the top of the building to be 4040 º. They the move 290290 feet closer to the building and find the angle of elevation to be 5151 º. Assume that the street is level, estimate the height of the building to the nearest foot.
