tính BC theo đvđd chứ bạn

Gọi độ dài AH = x ; HC = y ; BH = z; (x,y,z>0)

Ta có :

S_AHC  = xy=27 (1)

S_AHB = xz=48 (2)

Từ (1) và (2) ta có PT: 27z=48y(3)

mà x² =yz (hệ thức lượng trong tam giác vuông)(4)

từ (3) và (4) ta có HPT:

27z=48y;x² =yz

Bạn giải hệ này ra nhé!

x=6 ; y=4,5 ; z=8.

Vậy HB = 8 ; HC=4,5

=> BC = 12,5 (đvđd)
