Tolong secepatnya dijawab kk/bg mau dikumpul.besok

Jawaban:

Rumus

$ac = sqrt{ {ab}^{2} + {bc}^{2} }$

$ad = sqrt{ {ac}^{2} + {dc}^{2} }$

$ac = sqrt{ {12}^{2} + {9}^{2} }$

$ac = sqrt{ 144 + 81}$

$ac = sqrt{225}$

$ac = 15$

jadi panjang AC 15 cm

$ad = sqrt{ {15}^{2} + {8}^{2} }$

$ad = sqrt{ 225 + 64}$

$ad = 17$

jadi panjang AD 17 cm

semoga membantu
