Question

Intr-un triunghi dreptunghic ABC, m(<A)=90 grade, ADperpendicular pe BC, D apartine (BC):
a). BC=25CM CD=16CM Calculati BD AB si AC 
b). BC=20CM BD=16CM Calculati CD AB AC
c). AB=15CM BD=9CM Calcuati BC CD AC

Answer 1

BD=BC-DC=25-16=9
AB(la a 2a)=BC×BD=√25×9=√225=15
AC=20(Prin Pitagora)
