Question

A preengineering baseline was run down a very steep hill (see Figure).
The vertical angle is
turned to a point on a plumbed range pole
that is 4.88 ft above the ground. The slope distance from the theodolite to
the point on the range pole is 148.61 ft. The theodolite’s optical center is
4.66 ft (the height of the instrument) above the upper baseline station at
110+71.25. If the elevation of the upper station is 377.93, what is the
elevation of lower station? (15) What is the chainage (stationing) of the
lower station? (10) Note: The chainage is computed in the horizontal
plane
