Un triunghi dreptunghic ABC,m(A^)=90 grade,m(C^)=15 grade,iar mediana[am] (M)E BC are lungimea egala cu 24 cm. Aflati aria

Răspuns :

dac mediana are 24 decm, inseramna ca ipotenuza are 48cm
dac are un unghide 15 grade, ins3eamna ca inaltimea coresp ipoteb nuzei= ipotenuza/4=48/4=12cm
atunci aria=ipot*inalt coresp ipotenuzei/2=48*12/2=48*6=288cm²
as simple as that!!
