Question

construiti un triunghi MNP cu laturile direct proportionale cu 3 4 si 5 si perimetrul de 24 cm

Answer 1

{ m,n,p} d.p { 3,4,5 }
m+n+p= 24
m/3=n/4 = p/5 = K
m= 3k
n= 4k
p= 5k
3k + 4k + 5k = 24
12k = 24
k = 24:12
k= 2
m= 2*3 = 6
n= 4*2 = 8
p= 5*2 = 10

Answer 2

{x,y,z} d.p. cu {3,4,5}
x/3+y/4+z/5=k/1
x=3k, y=4k, z=5k
x+y+z= 24
3k+4k+5k=12k=24
k=2
x=6 cm, y=8 cm, z=10cm
MN=6 cm, MP=8 cm, NP=10 cm
