This website shows a picture of the angle in a free throw line. This is very important because free throw line is pretty hard to shoot because you can’t jump and if you jump that doesn’t count as a point so the way you do it is you need to have more power and force to reach the hoop.

This helps me because it’s important to know how hard is the free throw line and by doing that you need to have a greater angle to shoot.
