The backsight taken from BM#1 to BM#2 were 1.667 m, 0.579 m, and 2.234 m, the foresight readings were, 2.238 m from TP#1, and 1.936 m from BM#2. If the height of instrument for the first instrument setup is 99.918 m, and the difference in elevation between BM#1 and BM#2 is -0.911m, determine the elevation of TP#2.

Reciprocal leveling gives the following readings in meters from a set up near A: on A, 1.110; on B, 0.887, 0.995, and 0.884. At the setup near B: on B, 1.549; on A, 1.673, 1.670, and 1.666. The elevation of A is 1045.343 m. Determine the misclosure of B. Express your answer to three decimal places and include appropriate units. Misclosure = Submit Part B elevB = μÁ Value Request Answer CHA Value Units Determine the elevation of B. Express your answer to three decimal places and include appropriate units. Units ? ?

If you can help me with part b id greatly appreciate it, answer is not 10.77,10.72, 12.08, or 0.05. Thanks, will rate if answered within next couple hours.

Please help with b, i & ii The slope distance between two stations A and B measured with EDM when corrected for meteorological conditions and instrument constants, is 113.893 m. The heights of the instrument and reflector are 1.739 m and 1.839 m, respectively, above the ground. To measure the vertical angle a theodolite was set up at A, 1.665 m above the ground and a target at B having height above the ground as 1.632 m. The measured angle above the horizontal was + 4°22′18″. Determine a. The horizontal length of the line AB. b. To what precision the slope angle be measured: i. if the relative precision of the reduced horizontal distance is to be 1/100000. ii. if the reduced horizontal distance is to have a standard error of ± 1.8 mm.
