Question 22
In the figure below, $ABC$ is an isosceles triangle where $\angle A$ is a right angle, points $D$ and $E$ are on sides $AB$ and $AC$ respectively such that $AE\gt AD$. Let $F$ be a point on $AB$ such that $CF$ is parallel to $DE$. If $\angle ADE=4\angle BCF$, what is the measure, in degrees, of $\angle AED$?
