TB (True Bearing) = MB (Magnetic bearing) ± Declination
(Use + ve for eastern and – ve for western declination)
Calculation:
Given,
Declination = 5° 15' W
Magnetic bearing of Line = 135° 30'
TB (True Bearing) = MB (Magnetic bearing) - Declination
True Bearing = 135° 30' - 5° 15'
True Bearing = 130° 15'
