Răspuns :
daca notam laturile cu x,y,z avem
x/5=y/6=z/9=k
x=5k
y=6k
z=9k
5k+6k+9k=60 cm
20k=60
k=3
atunci
x=15 cm
y=18 cm
z=27 cm
x/5=y/6=z/9=k
x=5k
y=6k
z=9k
5k+6k+9k=60 cm
20k=60
k=3
atunci
x=15 cm
y=18 cm
z=27 cm
a,b,c- laturile triunghiului
a,b,c dp cu 5,6,9
a/5=b/6=c/9=k
a=5k
b=6k
c=9k
5k+6k+9k=60
20k=60
k=3
a=5*3=15
b=6*3=18
c=9*3=27
a,b,c dp cu 5,6,9
