Răspuns:
a) BC=75cm, AD=36cm, AB=45cm, AC=60cm;
b) se rezolva analog ...
Explicație pas cu pas:
BC=BD+CD=27+48=75, dUPA TEOREMA INALTIMEI AVEM: AD^2=BD*CD=27*48, De unde AD=RADICAL(27*48)=RADICAL(9*3*16*3)= 3*4*3=36, DECI AD=36.
aCUM FOLOSIM TEOREMA CATETEI: AB^2=BD*BC=27*75, DECI AB=RADICAL(27*75)=RADICAL(9*3*25*3)=3*5*3=45, DECI AB=45
ANALOG AFLAM CATETA AC: AC^2=CD*CB=48*75, DE UNDE AC=RADICAL(48*75)=RADICAL(16*3*25*3)=4*5*3=60, DECI AC=60
