Using the standard "compass heading"

that would be 120° based on standard trig notation.
what If I told you the plane ends up at
(125(1.5)cos120°, 125(1.5)sin125°) ??

I don't understand how you got 125 and 120°

330 clockwise from North is 360 - 30 = 30 degrees west of north
That is 90+30 = 120 in math talk counterclockwise from the x axis.
However being a navigator and not a mathematician I will stick with 30 degrees west of north:)
How far did it go?
125 *1.5 hours = 187.5 km
west = 187.5 sin 30 = 93.75 km
north = 187.5 cos 30 = 162.4 km
That is 90+30 = 120 in math talk counterclockwise from the x axis.
