Question

If BC = 15, BE = 6, DC = 12, and AD = 8,
then segment DE is parallel to segment
AB.

Answer 1

Do you have a picture? Your question isn’t making sense love

Answer 2

Solution: if BC = 15 - 6 = 9

Use the converse of triangle proportionality theorem

AD/DC = 8/12 = 2/3
BE/EC = 6/9 = 2/3

Answer: yes, AD/DC =BE/EC = 2/3, so DB||AB
