I remember seeing this problem on 4chan before (and that the system is underdetermined unless you draw new lines) but never really gave it an earnest attempt.

In hindsight it didn't require as much creativity as I anticipated, since the single heuristic
>see isoceles triangle
>draw line parallel to base
>apply triangle proportionality theorem
suffices to solve the problem when applied twice.
