no.23 ya. tolong! makasih

BC :
b = √c² - a²
b = √17² - 8²
b = √289 - 64
b = √225
BC = 15 cm

BE :
[tex] \frac{ab}{de} = \frac{bc}{ce} \\ \frac{8}{6} = \frac{15}{bc - be} \\ 6 \times 15 = 8(15 - be) \\ 90 = 12 0 - 8be \\ - 8be = 90 - 120 \\ - 8be = - 30 \\ be = 3.75[/tex]

Jawaban : D. 3,75 cm

Maaf Kalau Salah
