Question
An ocean liner is 177 miles due west of lighthouse A. Lighthouse B is 265 miles due south of lighthouse A. Find the distance from lighthouse B to the liner and the bearing of the ocean liner from lighthouse B.
Answers

distance is √(177^2 + 265^2)
bearing is (90-θ) where tanθ = -265/177
bearing is (90-θ) where tanθ = -265/177
