The side AB of an equilateral field ABC with an area of 692.80 sq.m. has a magnetic bearing of N48°45'E in 1930 when the magnetic declination was 0°52'E. Assume B and C is on the north-east side. a. b. C. Find the true bearing of AB. Find the length of AD with point D on the line BC and making the area of the triangle ABD one third of the whole area. Compute the bearing of line AD.
