- Panjang KL
[tex] \tt = \sqrt{ {17}^{2} - {8}^{2} } [/tex]
[tex] \tt = \sqrt{289 - 64} [/tex]
[tex] \tt = \sqrt{225} [/tex]
= 15 cm
- Panjang NL
[tex] \tt = \sqrt{ {10}^{2} - {8}^{2} } [/tex]
[tex] \tt = \sqrt{100 - 64} [/tex]
[tex] \tt = \sqrt{36} [/tex]
= 6 cm
- Panjang KN
→ KL - NL
→ 15 - 6 cm
→ 9 cm (C.)
