Question

Theorem: A line parallel to one side of a triangle divides the other two proportionately.

In the figure below, segment DE is parallel to segment BC and segment EF is parallel to AB:


Which statement can be proved true using the given theorem?

Segment BF = 9
Segment BD = 18
Segment BD = 20
Segment BF = 24

Answer 1

@zepdrix @eliesaab @Elsa213 please help me

Answer 2

If we look at the large triangle ABC
we can say that 15/25 = 12/DB

Answer 3

so the answer is B?
