you use wrong angle at N, it's not 36
it is 46°

500/sin(C)=720/(sin(46) => C=29.97°

third angle in triangle is 180°-(29.97°+46°)=104.03°

the bearing is
90°+46°+104.03°=240.03°
or 60.03° W

How did you get 46°? Why did you add 90° + 46° + 104.03°? What indicated this addition of angles in the photo?

 

[MathLover1]

you see at point Naples inner angle +44°=90° => inner angle is 90°-44°=46°

90° + 46° + 104.03° indicates total bearing
the bearing is
90°+46°+104.03°=240.03°
or S 60.03° W

Thank you. Good to have these notes for reference.
