Problem

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 the diagonals. If the measure of diagonal $AC$ is $11$ , then that of segment $EC$ is equal to

$\textbf{(A) }3\textstyle\frac{2}{3}\qquad \textbf{(B) }3\frac{3}{4}\qquad \textbf{(C) }4\qquad \textbf{(D) }3\frac{1}{2}\qquad \textbf{(E) }3$

Solution

$\fbox{E}$
