Question

A plane flies 400km west then 100km north .find its distance and bearing from its starting point

Answer 1

d^2 = 400^2 + 100^2
..
d = 412.3 km

If graphed, we are in quadrant II
tan(angle) = 100/400
angle = 14° from the horizontal

"bearing" is 270+14 = 284°

Answer 2

How is it 14 for the angle
