Question

Intr-un triunghi dreptunghic ABC, m(A)=90 grade, AD perpendicular pe BC , D apartine (BC) se dau:
a) AD= 24 cm si BD= 18cm . Calculati CD si BC
b) BD= 8 cm si CD= 0,18 m. Calculati AD si BC
Va rog mult sa ma ajutati :))))

Answer 1

AD^2 =BD *CD
24^2 =18*CD
576 =18*CD
CD =576/18 =32 cm
BC =BD+CD =18+32 =50 cm
b) AD^2 =BD+CD 
AD^2 =8*18 =144      ( 0.18m =18 cm)
AD =12 cm
BC =BD+CD =8+18 =26 cm
