26. Perhatikan gambar berikut! Jika panjang AB = 15, panjang BE adalah? A. 12 cm B. 9 cm C. 8 cm D. 6 cm 27. Perhatikan gambar disamping! Panjang EF adalah? A.

26. 
[tex] \frac{AB}{BC} = \frac{DE}{CE} \\ \frac{15}{12+BE} = \frac{10}{12} = \frac{5}{6} [/tex]

kali silang

15 x 6 = (12+BE) 5
90 = 60 + 5BE
5BE = 90 - 60
        = 30
BE = 30/5 = 6


27.

22-7 = 5

5 x [tex] \frac{6}{6+4} [/tex]
= 5 x [tex] \frac{6}{10} [/tex]
= 3

7+3 = 10
