In determining the difference in elevation between points A and B, the inclined distance was measured to be 157.65 ft.
The transit was setup on point A. The height of its transverse axis was 5.2 ft above point A
The instrument had an index error of +4'.
A rod was held on point B and the telescope is inclined so that the horizontal cross line of the transit intersects the rod at the 5.2 ft mark.
If the reading on the vertical limb of the transit was +25° 19', what was the difference in elevation between the two points?
