North direction leg 760 km
Westward direction leg, x
The two legs meet at 90 degree angle.
Angle at the north: 50 degrees
Angle at the west: 40 degrees.

I used the 220 degree bearing according to 0 degrees being directly Eastward, so as to be the same direction as used on the Unit Circle. East, like the positive direction on the x-axis. This way 180 degrees is all the way West, and 220 degrees is 220-180=40 degrees downward from West.
