Question

A golfer hits a tee shot on a 350m long straight golf hole. The ball is hooked (hit at an angle) 21 degree to the left. The ball lands 210m from the tee. How far is the ball from the hole?

I know how to solve this using cosine law (171.35 m) but am having trouble drawing the triangles.
what? eh? huh?

Mark point T (the tee)
Mark point H (the hole)
Draw the line TH.

Draw angle at T 21° from the line TH.
Mark point (B) on that line roughly 3/5 as far from T as H is.

Can you see the triangle?
