Question

Help with geometry question please

Answer 1

AE is twice the size as BD

Answer 2

How did you figure that out

Answer 3

unfortunatly i dont know how to explain it xD i guess it's a matter of ratios of the sides

Answer 4

ok Thanks :)

Answer 5

@nyk

The theorem you need for this problem is the following:

The segment joining the midpoints of two sides of a triangle is parallel to and has half the measure of the the third side.

That means that BD = (1/2)* AE

3x + 5 = (1/2) ( 4x + 20 ) --> Solve for x.
