Jr, a civil engineer was to estimate the height of a transmission tower (G). He performed trigonometric leveling from 3 stations E, Y&A, using slope distances and vertical angles. The survey data are as follows: SEG = 678.56; aEG= 5°30' Syg = 555.31; aye= 3°10' SAG = 900.31; a 46= 2°45' Elevations of stations above the MSL datum HE = 253.31 ft| Hy= 287.64 ft. H= 275.11 ft. Compute the elevation at the top of the cell tower from pt. Y Select the correct response: 412.35 ft 318.32 ft 253.32 ft 320.35 ft

Surveying is the practice to determine the relative three-dimensional positions of various points on the earth’s surface. This is done by computing the vertical and horizontal distances, angles between the points, collecting the observations, and plottin…
