ditanya :

tentukan nilai x dan y ......?

jawab

[tex] \frac{x}{x + 2} = \frac{6}{10} \\ 10x = 6x + 12 \\ 4x = 12 \\ x = \frac{12}{4} \\ x = 3 \\ \\ \frac{y}{10} = \frac{6}{10} \\ y = \frac{10 \times 6}{10} \\ y = 6[/tex]

semoga membantu

Jawaban:

Answer+Explain:

Diketahui:

  • BC = 10 cm
  • AD = 6 cm
  • DB = 4 cm
  • AB = 4 cm + 6 cm = 10 cm
  • EC = 2 cm

Penyelesaian:

a.) mencari nilai x

[tex]\frac{AD}{AE} = \frac{DB}{EC} \\ \\ \frac{6}{x} = \frac{4}{2} \\ \\ x = \frac{6 \times 2}{4} \\ \\ x = \frac{12}{4} \\ x = 3 \: cm[/tex]

b.) mencari nilai y

[tex]\frac{ED}{CB} = \frac{AD}{AB} \\ \\ \frac{y}{10} = \frac{6}{10} \\ \\ y = \frac{6 \times 10}{10} \\ y = 6 \: cm[/tex]

note:

  • dalam operasinya menggunakan perkalian silang
