8) The figure shows part of a common roof design using very strong and stable triangular trusses. Points \(B, C, D, F, G,I\) and \(J\) are midpoints of \(\overline{AC}, \overline{AE}, \overline{CE}, \overline{GE}, \overline{HE},\overline{AH}\), and \(\overline{AI}\) respectively. What is the total length of all the stabilizing bars inside \(\triangle AEH\)? Explain how you calculated the answer.
