Jawab:

AB = 14 cm

Penjelasan dengan langkah-langkah:

AC² = AD² – CD²

AC² = 26² – 10²

AC² = 676 – 100

AC² = 576

AC = √576

AC = 24 cm

AC = AB + BC , dimana BC = CD = 10cm

AB + BC = AC

AB = AC – BC

AB = 24 – 10

AB = 14 cm

Penjelasan dengan langkah-langkah:

{cd}^{2} + {ac}^{2} ={ad}^{2} \ {10}^{2} + {ac}^{2}={26}^{2}\ {ac} = sqrt{ {26}^{2} - {10} ^{2} } \ {ac}= sqrt{676 - 100} \ ac = sqrt{576} \ ac = 24

CD = BC = 10

AB = AC – BC

AB = 24 – 10

AB = 14
