An ornithologist tracks a bird forming a triangular flight path between points $ A(0, 0) $, $ B(8, 0) $, and $ C(0, 6) $, calculating its energy expenditure as proportional to the area. If a competing geometric model uses a right-angled triangle with one leg equal to $ AB $ (length 8) and the same area, what is the length of the other leg? - Sterling Industries
