Render 4 quick drawings

I'm trying to design golf putting mats. The putting stroke has an arc to it which ranges between 12 and 21 degrees. I am looking for drawings of arcs 12, 15, 18, and 21 degrees.

The putting matts I'm creating will be 60 inches wide and 9 inches tall.

Here is a video explaining precisely what I'm looking for: https://www.loom.com/share/c29cb368252b4eed8f672079b4b253fb
