Question

Un triunghi ABC are aria 24 cm patrati ,AB =6 cm ,BC= 8 cm si Ac = 10 cm .Calculati lungimile inaltimilor triunghiului

Answer 1

AriaABC=l1*h1 supra 2
AB*h1 supra 2=24
6*h1 supra 2=24
3*h1=24
h1=8
BC*h2 supra 2=24
8*h2 supra 2=24
4*h2=24
h2=6
AC*h3 supra 2=24
10*h3 supra 2=24
5*h3=24
h3=24 supra 5
h3=4,8

Answer 2

A =AB*h /2
24 =6*h /2
h =24*2 /6\48/6 =8 cm

A =BC*h =2
24 =8*h =2
h =24*2 /8 =48/8 =6 cm

A =AC*h/2
24 =10*h /2 
h =24*2/10 =48/10 =4.8 cm
