A ship is 90 miles south and 20 miles east of port. The captain wants to travel directly to port. What bearing should be taken?

MathMate,
"90 miles south and 20 miles east of port"
means the direction along which the ship must sail is:
x=90, y=20
angle = atan(20,90) = 180°  12°31'44"
= 167°28'16" (in trigonometry notation).
To convert trigonometry notation to bearing, subtract angle from 90° or 450° if the angle exceeds 90°.
Bearing (clockwise from north)
= 450°  167°28'46"
= 282°31'44"
