Prob. 22. Let J^G and GIf he two parts of a straight line, each800 feet long. At J^, G, and H are measured the angles whichlines from a station S make with the base, namely, SFG = 40° i2,FGS = 92° 58, and GUS = 43° 55. Compute the length of GSin two ways, and, if they are not equal, find the most… … subtended at it by three stations A, B, and C whose positionsare known. It is well to measure the three angles at 6 andthen by the station adjustment find the most probable values 23. THE THREE-POINT PROBLEM. 65 of 5, and 5,. The data of the three known points give thedistances AB and BC which will…
