Question

In triunghiul ABC avem : m ( < A ) = 90° , AE perpendicular pe BC , E apartine BC . Daca CE = 25 cm si EB = 16 cm , calculati : a) Lungimea inaltimii AE .

Answer 1

ΔBAC-Δdreptunghic
m(<A)=90 de grade
Aplicam prima teorema a inaltimii intr-un triunghi dreptunghic si obtinem
AE=√CE·EB
AE=√25·16
AE=√5²·4²
AE=5·4=20(cm);
