After my work, I got S23.4degreesE but the book's answer is

S76.6degreesE.

How do I get the book's answer? Why is my answer wrong?

- Find Airplane Bearing -
**Reiny**, Friday, February 22, 2008 at 8:00pmlet's give some letter names to our triangle

let the origin be O

let the end of the first leg be A, the end of the second leg be B

then OA=.5 and AB = 1 and angle A = 90º

so by Pythagoras OB = 1.118

and angle AOB = 63.4

so the plane is flying 103.43 from north

which when subtracted from 180 is 76.57º as your book says
