How was trigonometry used to define this racing line

I was searching through the internet for an equation that defines the path followed by a racing line, when I came across the following formula on StackExchange posted by another user as a reply for another user. However, I could not understand what kind of maths is being used in the proof submitted by this user:
I created this account, but couldn't comment on the user's proof, so I decided to post it as a question. I would appreciate it if someone was able to explain to me just what kind of maths was used to solve the problem.
I understand that it involves trigonometry, but I can't seem to figure out exactly how he used it to solve this problem and how he applied trigonometry to solve it, as I don't think I have advanced that far in maths.
I am not sure how I am supposed to apply trigonometry here because I honestly cannot understand how each he (or she) transitions from the first equation to the second and then to the third.

It's just trigonometry.

It's geometry/trig in making the biggest radius from the outside of the roadway at the start of the turn, to the inside closest to the inside corner or apex, and back to the outside.

See Beckman’s old “Physics of Racing” papers for this and other fun stuff. Part 5 in particular covers this.
