Answer 1

Jawaban:

a. EB = 12/5 cm ; b. CE = 8 cm

Penjelasan dengan langkah-langkah:

a. ∆ABC sebangun ∆DEC

maka CB/CE = AB/DE; Mis EB= X

[tex] \frac{6 + x}{6} = \frac{7}{5} [/tex]

[tex]5(x + 6) = 7 \times 6[/tex]

5x + 30 = 42 <=> 5x = 12 maka x = 12/5

b. ∆ABC sebangun ∆EBD

maka BC/BD = AB/EB; mis CE = X

[tex] \frac{x + 4}{6} = \frac{8}{4} = 2[/tex]

x + 4 = 12 maka x = 8
