Question

BC¯¯¯¯¯ is parallel to DE¯¯¯¯¯. What is CE? Enter your answer in the box.

Answer 1

10

Explanation:

i just took the test and got it right.

Answer 2

Hence, CE=10

Explanation:

" Triangle Proportionality Theorem: If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally "

i.e.

Here we have:

BC||DE. (i.e. BC is parallel to DE).

Hence we have:

`(AB)/(BD)=(AC)/(CE)`

Here we have:

`AB=15, BD=6, AC=25`

Hence,

`(15)/(6)=(25)/(CE)\\\\CE=25* (6)/(15)\\\\CE=10`

Hence, the length of CE is 10 units.
