Sample Problem 6.4A property line surveyed in 1975 by Engr. Carasco. The line was recorded with amagnetic bearing of S 57° 28' 15" W. The magnetic declination at the time of surveywas 2° 43' E. Determine the true bearing and the azimuth of the property line (fromNorth).Solution:MN2° 43'Property LineFigure 6.16 Illustration of Sample Problem 6.4The easiest way in dealing with angles is to illustrate the situation. After the illustration,the bearing and azimuth are determine mathematically based on the Figure.The magnetic declination is given with the magnitude of 2° 43' E. This means that themagnetic pole is inclined 2° 43' to the East of the true North.For the true bearing:The bearing of a line can be measure from either North or South Pole as long as itsvalue is in between 0 to 90 degrees. In this problem, we will measure the bearing fromSouth to meet the bearings criterion.Ob True = 57° 28'15" + 2° 43'Өъ Тrие — S 60° 11'15" WFor the azimuth:The azimuth should be measure from North as stated in the problem.a True = 180° + 60° 11'15"Oa True = N 240° 11'15"The true bearing of the property line is S 60° 11'15" W and its true azimuth with respectto North is 240° 11'15".
