problem on a trapezoid having intersection of diagonals
This problem is hard for me. Can anyone help me? Thank you in advance.
Let ABCD be a trapezoid with the measure of base AB twice that of base DC, and let E be the point of intersection of diagonals. If the measure of diagonal AC is 11, then that of segment EC is equal to?

triangles ABE and CDE are similar, hence: $frac{AB}{DC}=frac{AE}{CE}=2$ and AE+EC=11. Hence, EC=$11/3$.
Thanks. I think that my brain did not work.
