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; arg= 5°30' Syg = 555.31; ay= 3°10' SAG = 900.31; a s= 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. E Select the correct response: 253.37 ft 318.35 ft 412.37 ft 320.32 ft
