In surveying, the true bearing of a line is 180° 00′ and magnetic declination is 4° 30′ West. What is the magnetic bearing of the line?
A175° 30'
B184° 30'
C180° 00'
D174° 30'
Explanation
True Bearing (TB) = Magnetic Bearing (MB) – Declination West. Therefore, Magnetic Bearing = True Bearing + West Declination = 180° 00′ + 4° 30′ = 184° 30′.
