Met de stelling van Pythagoras:

$ \begin{array}{l} \left\{ \begin{array}{l} a = 12 \\ (24 - c)^2 + b^2 = \left( {b + c} \right)^2 \\ 12^2 + \left( {24 - b} \right)^2 = \left( {a + b} \right)^2 \\ \end{array} \right. \\ ... \\ \left\{ \begin{array}{l} a = 12 \\ b = 8 \\ c = 9 \\ \end{array} \right. \\ \end{array} $
