Magnetic Declination: 1. In a compass survey made twenty years ago the observed magnetic bearing of a reference line XY was S 42'21" W when the magnetic declination was 7'45' west. Lately in 2018, a new survey was made and the declination in the same survey site changed to 9'12" East. Determine the following descriptions of line XY: a.) Its true bearing twenty years ago; b.) The true azimuth from North and South; c.) Its new magnetic bearing; and d.) The magnetic azimuth from North and South in 2018.
