Penjelasan dengan langkah-langkah:

[tex] \frac{9}{y} = \frac{9 - 4}{5} [/tex]

[tex]y = 9 \: cm[/tex]

[tex] \frac{12 - x}{12} = \frac{5}{y} [/tex]

[tex] \frac{12 - x}{12} = \frac{5}{9} [/tex]

[tex]60 = 108 - 9x[/tex]

[tex]9x = 108 - 60[/tex]

[tex]9x = 48 \\ x = \frac{48}{9} \\ x = 5 \frac{3}{9} = 5 \frac{1}{3} \: cm[/tex]
