Question

In triunghiul ABC m∡(A) = 90 de GRADE, AD⊥BC avem CD=4 si BD=8.Aflati inaltimea AD.
URGENT !

DAU COROANA !!!!!!!!

Answer 1

AD patrat = BD x DC
AD patrat = 8 x 4 = 2 x 4 x 4
AD = 4 radical din 2

Answer 2

ΔABC dreptunghic si AD -inaltimea ⇒ Aplicam teorema inaltimii
AD² = BD x DC
AD² = 4 x 8
AD² = 32
AD=√32
AD= 4√2 cm
