AB = 158 cm
BC = 576 cm
BE = 155 cm
CD = ?
Keadaan tersebut membentuk segitiga sebangun. yaitu ΔACD dan ΔABE. Maka lakukan perbandingan:
[tex]\sf\frac{AB}{AC} =\frac{BE}{CD} \\\\\frac{158}{158+576} =\frac{155}{CD} \\\\\frac{158}{734} =\frac{155}{CD}\\\\\frac{79}{367} =\frac{155}{CD}\\\\79CD =367(155)\\\\79CD=56.885\\\\CD=\frac{56.885}{79} \\\\CD=720,063...[/tex]
∴ CD ≈ 720 cm
kesebangunan
BE/CD = AB/AC
CD = BE × AC/AB
panjang CD
= 155 × (576 + 158)/158
= 155 × 4,646
= 720,13 cm
