21) when a compass survey was run in 1950, the magnetic declination was 10°15' cast. The magnetic
bearings of several lines observed then were recorded as follows:
a.) AB, N 25° 15' W
d) DE $50°OD'E (1)
12.) BC, $ 14° 38' E e) EF, N 86°29¹ W
C) CD. N 05° 20'E
:.) FG, S15° 30¹ W
If these lines are to be retracted using a compass when the declination is 15°12' west, determine the new
magnetic bearings to be set OFF on the compass.YAS
