In an old survey performed in 1965, a line AB had a magnetic bearing of S75o10’W when the magnetic declination was 4o30’ west. In a new survey performed in 1987, the declination in the same locality changed to 2o50’ east. Determine the true bearing of AB in 1965, the magnetic bearing of AB in 1987, the true azimuth (from the north) of AB in 1987, and the back azimuth (from the south) of AB in 1965.

Question

In an old survey performed in 1965, a line AB had a magnetic bearing of
S75o10’W when the magnetic declination was 4o30’ west. In a new survey
performed in 1987, the declination in the same locality changed to 2o50’ east.
Determine the true bearing of AB in 1965, the magnetic bearing of AB in 1987, the true azimuth (from the north) of AB in 1987, and the back azimuth (from the south) of AB in 1965.
