AC =
$sqrt{ {ab}^{2} + {bc}^{2} }$
AC =
$sqrt{144 + 81}$
AC = akar225
AC = 15

AD^2 = AC^2 + CD^2
AD^2 = 225 + 64
AD^2 = 289
AD = 17 cm

AC = √AB² + BC²
AC = √12² + 9²
AC = √144 + 81
AC = √225
AC = 15 cm

Cari panjang AD atau sisi miring
AD = √AC² + CD²
AD = √15² + 8²
AD = √225 + 64
AD = √289
AD = 17 cm
