dit :
panjang AD adalah...​

Penjelasan dengan langkah-langkah:

AC² = AB² + BC²

[tex]ac = \sqrt{ {ab}^{2} + {bc}^{2} } \\ \: \: \: \: = \sqrt{ {12}^{2} + {9}^{2} } \\ \: \: \: \: = \sqrt{144 + 81} \\ = \sqrt{225} \: \: \: \: \: \\ = 15 \: \: \: \: \: \: \: \: \: \: \: \\ [/tex]

AD² = AC² + CD²

[tex]ad = \sqrt{ {ac}^{2} + {cd}^{2} } \\ \: \: \: \: = \sqrt{ {15}^{2} + {8}^{2} } \\ \: \: \: \: = \sqrt{225 + 64} \\ = \sqrt{289} \: \: \: \: \: \\ = 17 \: \: \: \: \: \: \: \: \: \: \: [/tex]

Jadi, panjang AD adalah 17 cm.
