Question

Un triunghi are lungimea de 80 si latimea de 60 aflati diagonala

Answer 1

$d= \sqrt{L^2+l^2}= \sqrt{80^2+60^2}= \sqrt{6400+3600}= \sqrt{10000}=100.$

Answer 2

$Poti$ $afla$ $diagonala$ $folosind$ $un$ $fel$ $de$ $Teorema$ $lui$ $Pitagora.$ 
$d^{2} = AC^{2}+ AB^{2}= 80^{2}+ 60^{2}=6400+3600=10000$
$d= \sqrt{10000}=100$
