Question:

(4a) If the geodetic azimuth of a line is 65 06' 59.8", the convergence angle is 1 24' 32.2", and the arc-to-chord correction is -1.2", what is the equivalent grid azimuth for the line?

(4b) If the geodetic azimuth of a line is 308 06' 16.97", the convergence angle is -1 48' 36.8", and the arc-to-chord correction is -1.5", what is the equivalent grid azimuth for the line?

(4c) Using the values given in Problems (4a) and (4b), what is the obtuse grid angle between the two azimuths?
