Art. 2.4.3 of the FIBA official rules (approved 4th July 2017) says that
The free-throw line shall be drawn parallel to each endline. It shall have its furthest edge 5.80 m from the inner edge of the endline and shall be 3.60 m long
But in Diagram 2 of the same rules, the free-throw line is 4.9 m long (and not 3.6)
Am I missing something?
