Question

di tanyakan berapakah panjang AE tersebut?​

Answer 1

Jawaban:

Penyelesaian :

• AB = 12 cm
• BC = AD = 26 cm
• EC = 22 cm

Panjang sisi AE

[tex] \sf ED = EC - AB \\ \sf ED = 22 - 12 \: \: \\ \sf ED = 10 \: cm \: \: \: \: \: [/tex]

[tex] \sf {AE}^{2} = {AD}^{2} - { ED}^{2} [/tex]

[tex] \sf {AE}^{2} = {26}^{2} - {10}^{2} [/tex]

[tex] \sf {AE}^{2} = 676 - 100[/tex]

[tex] \sf {AE}^{2} = 576[/tex]

[tex] \sf AE = \sqrt{576} [/tex]

[tex] \sf AE = 24 \: cm[/tex]
