Find the true bearing of the lines with the following observed magnetic bearings and declinations.  (a) Bearing of line  = 189°12. Declination = 2° W (b) Bearing of line  = 72° 44′ Declination = 1° 12 ‘ E solutions : (a) True bearing of line= magnetic bearing of line – Declination (West) = 189° 12′ … Read more
