We can use the sine rule to find the hole angle, and then find the golfer angle:


(200)/(\sin(115))=(140)/(\sin (Hole))
\text{Hole Angle = }\sin ^(-1)((140*\sin (115))/(200))
\text{Hole Angle = }39.37664303\text{ degre}es

Now we can find the golfer angle:


\text{Golfer = 180 - 115 - 39.38 }\cong25.6\text{ degre}es

Answer: 25.6 degrees.
