Question

Sa se afle o cateta a unui triunghi dreptunghic cu aria de 60 cm la puterea a doua si lungimea celeilalte catete de 6 cm.

Answer 1

aria = cat ·cat /2
6 ·cat /2 = 60 
cat /2 = 10 
cateta ceruta = 20 cm

Answer 2

$A= \frac{ c_{1}*c_{2} }{2}$
$60= \frac{6* c_{2}}{2} =\ \textgreater \ c_{2}=\frac{60*2}{6}= \frac{120}{6} =20 cm$
