An EDM slope distance AB is determined to be 561.276 m. The EDM instrument is 1.820 m above station A, and the prism is 1.986 m above station B. The EDM in- strument is mounted on a theodolite whose optical center is 1.720 m above the sta- tion. The theodolite was used to measure the vertical angle (+6°21'38') to a target on the prism pole; the target is 1.810 m above station B. Compute both the horizon- tal distance AB and the elevation of station B if the elevation of station A = 186.275 m.
