Question: In trigonometric leveling from point A to point B , the slope distance and zenith angle measured at A were 2 4 6 5 .

In trigonometric leveling from point A to point B, the slope distance and zenith
angle measured at A were 2465.46ft and 9308'36''. At B these measurements
were 2465.58ft and 8651'32'', respectively. If the instrument and rod target
heights were equal, calculate the difference in elevation from A to B.
