5. The coordinates with standard deviations of two stations A and B were determined as given below. Calculate the length and standard deviation of AB. Station Easting 456.961 m 20 mm 724.616 m+ 40 mm A B Northing 573.237 m ± 30 mm 702.443 m 50 mm The length of AB was independently measured as 297.426 m ± 70 mm and its separate determination by EDM is as 297.155 m ± 15 mm. Calculate the most probable length of the line and its standard deviation.
