The Earth's radius is about 4000 miles. Kampala, the capital of Uganda, and Singapore are both nearly on the equator. The distance between them is 5000 miles.Through what angle do you turn, relative to the earth, if you fly from Kampala to Singapore?
the only thing i can think of doing is using the law of cosines, if both sides equal 4000 miles and the other side of the tirangle is equal to 5000k miles...but i tried that it doesn't work..i tried using all the trig functions and it still didnt work..would someone just point me to the direction that will get me started...
