101 Sample Write-Ups for Documenting Employee Performance Problems: A Guide to Progressive Disc

Matematika perhatikan gambar berikut.AB=8cm,BC=6cm,dan CD=26cm​

perhatikan gambar berikut.AB=8cm,BC=6cm,dan CD=26cm​

Diketahui :

panjang AB = 8 cm

panjang BC = 6 cm

panjang CD = 26 cm

Ditanya :

panjang AD = ...?

Jawab :

* mencari panjang AC

[tex]ac = \sqrt{ {ab}^{2} + {bc}^{2} } \\ ac = \sqrt{ {8}^{2} + {6}^{2} } \\ ac = \sqrt{64 + 36} \\ ac = \sqrt{100} \\ ac = 10 \: cm[/tex]

* mencari panjang AD

[tex]ad = \sqrt{ {cd}^{2} - {ac}^{2} } \\ ad = \sqrt{ {26}^{2} - {10}^{2} } \\ ad = \sqrt{676 - 100} \\ ad = \sqrt{576} \\ ad = 24 \: cm[/tex]

Jadi, panjang AD adalah 24 cm.
