Three altitudes

A triangle with altitudes 4; 5, and 6 cm is given. Calculate the lengths of all medians and all sides in a triangle.

Correct answer:

a =  7.5236 cm
b =  6.0189 cm
c =  5.0157 cm
t1 =  4.0671 cm
t2 =  5.6413 cm
t3 =  6.3345 cm

Step-by-step explanation:

v1=4 cm v2=5 cm v3=6 cm  h=1/v1+1/v2+1/v32=1/4+1/5+1/62=371200.3083 t=h (h1/v1) (h1/v2) (h1/v3)=0.3083 (0.30831/4) (0.30831/5) (0.30831/6)0.0003  s=4 t=4 0.00030.0665 S=1s=10.066515.0472 cm2  S=a v12  a=2 S/v1=2 15.0472/4=7.5236 cm
