Multiple choice Track = 090, Variation = 5 degrees west. Magnetic course = 085 090 095 100 Reveal answer Fill a bubble to check yourself C Correct answer Explanation When variation is west, add it to true course to get magnetic course. Track 090 + Variation 5° west = Magnetic course 095. West variation requires adding. 085 would be for east variation, 090 ignores variation, 100 is incorrect arithmetic.
