Convoy Interception Methods

Anyone here decent at trig? I'm actually trying to make that manual lead table value but I keep coming up sour mathematically. The setup is pretty simple, three dots on a page, submarine position, target position, and intercept location. I know that all you need to find out your lead angle is the ratio of target/submarine speeds and the AoB angle.

An example would be something like "Target is half my speed, AoB is 120 degrees... lead angle solution is 22 degrees." You point 22 degrees from directly at the target in the direction it's moving and you run into it some time later with a big clang of metal.
