**word problem**

the plane is traveling South with the wind at 37 miles per hour It is flying North in the air at 450 cos 60 = 225 so its speed North = 225 - 37 = 188 its speed East is 450 sin 60 = 389 so total speed = sqrt(188^2 + 389^2) =sqrt (186665) = 432 mph tan angle east of north = 389/...

**Math**

In still air a plane has air speed 300km/h and flies on a bearing of 110 degrees. If the wind is blowing at a speed of 100km/h from a bearing of 60 degrees, find the actual velocity of the plane.

Trig - Damon, Sunday, March 3, 2013 at 6:24pm East speed = 100 + 200 sin 45 = 241 North speed = 200 cos 45 = 141 speed = sqrt( 141^2 + 241^2) = 279 mph tan east of north = 241/141 so angle east of north = 60 degrees
