Question

aflati masurile ungiului unui triunghi stiind ca sunt direct proportionale cu 4,5 si 6

Answer 1

frac{x}{4} = \frac{y}{5} = \frac{z}{6} = \frac{x+y+z}{4+5+6} =k;[tex] \frac{180}{15} =12;X=12x4=48,Y=12x5=60,Z=12x6=72.

Answer 2

a/4=b/5=c/6=k a=4k b=5k c=6k
a+b+c= 180grade 4k+5k+6k=180
15k=180
k=180:15=12
a=4*12=48grade
b=5*12=60grade
c=6*12=72grade
