A__________C__________D__________B

Answer 1

   
[tex]\displaystyle \text{Voi atasa fotografia paginii:} \\ \\ 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} [/tex]


[tex]BD ~se ~intinde ~ pe~5~patratele. \\ \\ \Longrightarrow ~~BD = \frac{8}{15} \times 5 = \frac{8 \times 5}{15} = \boxed{\frac{8}{3}\;cm} [/tex]
