Using the values given in Problems 20.40 and 20.41, what is the obtuse grid angle between the two azimuths?
Problem 20.40:
If the geodetic azimuth of a line is 205°06'36.2", the convergence angle is -0°42'26.1" and the arc-to-chord correction is +0.8", what is the equivalent grid azimuth for the line?
Problem 20.41:
If the geodetic azimuth of a line is 18°47'20.1", the convergence angle is -1°08'06.8" and the arc-to-chord correction is -1.5", what is the equivalent grid azimuth for the line?
