Question

What is the length of Line segment D C? 2 units 3 units 6 units 9 units

Answer 1

the answer is 3 units

Answer 2

Answer:

DC=3 units

Explanation:

From the given figure, it can be seen that DE is parallel to BC, thus by using the basic proportionality theorem, we get

AE/EB=AD/DC

⇒12/4=9/DC

⇒DC x 12=9 x 4

⇒DC x 12=36

⇒DC=36/12

⇒DC=3

Thus, the length of DC will be =3 units.
