Mr. Brown is plotting a regular hexagonal field ABCDEF in California. He starts by measuring line AB at a bearing of N 5°30’ E. Unfortunately, he forgot to take into account the magnetic declination of California, which is 2°20’ W. What will be the azimuths from the north of all the lines of the hexagonal field if magnetic declination was considered? Also draw the hexagonal field with all the necessary angles.
