ta có :\(\frac{x}{3}=\frac{y}{-3}\)
=>\(\frac{x^2}{3^2}=\frac{y^2}{\left(-3\right)^2}=\frac{x^2+y^2}{9+9}=\frac{25}{18}\)
=>\(\frac{x}{3}=\frac{25}{18}\Rightarrow x=\frac{25.3}{18}=\frac{25}{6}\)
=> \(\frac{y}{-3}=\frac{25}{18}\Rightarrow y=\frac{25.\left(-3\right)}{18}=-\frac{25}{6}\)
=>\(\frac{z}{6}=\frac{25}{18}\Rightarrow z=\frac{25.6}{18}=\frac{25}{3}\)
