đặt a = AB = AC

Áp dụng định lý pytogo trong tam giác vuông ta có 

\(a^2+a^2=BC^2\Rightarrow2a^2=12^2=144\Rightarrow a^2=72\Leftrightarrow a=\sqrt{72}=6\sqrt{2}\)

vậy, AB = AC = \(6\sqrt{2}\)

tham khảo ạ

 +  +  ≥ 3.

Đặt b + c – a = x > 0 (1); a + c – b = y > 0  (2); a + b – c = z > 0  (3)

Cộng (1) và (2) => b + c – a + a + c – b = x + y ⇔ 2c = x + y ⇔ c = 

Tương tự a =  ; b = 

Do đó  +  +  =  +   +  = ( +  +  +  +  + )

= [( + ) + ( + ) + ( + )] ≥ (2 + 2 + 2) = 3.

Vậy  +  +  ≥ 3.
