The length of BC is 6. The smaller triangle AEB has AE=16
And triangle ADC, ED=8 which is half of 12. So BC has to be half of AB, making length BC 6

Answer:

BC = 6 units

Step-by-step explanation:

In triangle ACD, BE || CD (given)

Therefore, by Basic Proportionality Theorem, we have:

[tex]\frac{AE}{ED} =\frac{AB}{BC} \\ \\ \therefore \: \frac{16}{8} = \frac{12}{BC} \\ \\ \therefore \: \frac{2}{1} = \frac{12}{BC} \\ \\ \therefore \: BC = \frac{12}{2} \\ \\ \therefore \: BC =6 \: units[/tex]
