Golfer's Putt Challenge: Angle & Displacement

[p5oct]

A golfer lines up for her first putt at a hole that is 13 m exactly northwest of her ball’s location. She hits the ball 13 m and straight, but at the wrong angle, 39° from due north.
a) In order for the golfer to have a “two putt green,” determine the angle of the second putt.? ___________________°south of west
b) Determine the magnitude of the second putt's displacement. _________________m

I presume you are after a hint? Draw a diagram - a reasonably accurate diagram!

What Peter said. Draw the diagram. The fact that she hit the putt the right distance might help simplify the maths a bit.
