AB = 8\;cm
\text{Pe orizontal, [AB] se intinde pe 15 patratele} \\ \\
O ~patratea = \frac{8}{15}\;cm \\ \\
AC ~se ~intinde ~ pe~5~patratele. \\ \\
\Longrightarrow ~~AC = \frac{8}{15} \times 5 = \frac{8 \times 5}{15} = \boxed{\frac{8}{3}\;cm} \\ \\
CD ~se ~intinde ~ pe~5~patratele. \\ \\
\Longrightarrow ~~CD = \frac{8}{15} \times 5 = \frac{8 \times 5}{15} = \boxed{\frac{8}{3}\;cm}
