Cari panjang dari AC dulu ya ka:)AC = √AB²+BC²
= √8²+6²
= √64+36
= √100
= 10 cm
Baru bisa dicari panjang AD
AD = √CD²-AC²
= √26²-10²
= √676-100
= √576
= 24 cm ^^

AC^2 = AB^2 + BC^2AC^2 = 8^2 + 6^2
AC^2 = 64 + 36
AC^2 = 100
AC = √100 = 10 cm
maka
AD^2 = CD^2 - AC^2
AD^2 = 676 - 100
AD^2 = 576
AD = √576 = 24 cm (D)
semoga membantu :)
