MAGNETIC DECLINATION<br />
Find magnetic declination for 1993 (angle MN TN)<br />
9°39' - 0°31' = 9°08'<br />
Determine total change<br />
Years passed: 2010 – 1993 = 17<br />
17 * 0°4.3' = 73.1' 1°13.1'<br />
Add change to 1993 declination<br />
9°08' + 1°13.1' = 10°21.1'<br />
Therefore: the magnetic declination<br />
for 2010 would be 10°21.1'
