jawab pakai cara ya kak besok sudah harus dikumpul

5. a.
[tex]ad = \sqrt{ {ab}^{2} - {bd}^{2} } \\ = \sqrt{ {26}^{2} - {10}^{2} } \\ = \sqrt{676 \: - \: 100} \\ = \sqrt{576} \\ = 24 \: cm[/tex]
5. b.
[tex]ac = \sqrt{ {ad}^{2} + {dc}^{2} } \\ = \sqrt{ {24}^{2} + {18}^{2} } \\ = \sqrt{576 + 324} \\ = \sqrt{900} \\ = 30 \: cm[/tex]
