In a region with magnetic declination of 2oE, the magnetic Fore bearing (FB) of a line AB was measured as N79o50’E. There was local attraction at A. To determine the correct magnetic bearing of the line, a point O was selected at which there was no local attraction. The magnetic FB of line AO and OA were observed to be S52o40’E and N50o20’W, respectively. What is the true FB of line AB?
Correct : c
