Determine the angle at E: $\displaystyle \tan(E)=\frac{10}{24}$ 2. Now you know all interior angles of the triangle EDA. Use Sine rule to calculate the length of AD.
if you don't know sine rule yet: draw a line from A perp to EB, call that intersection F get angle E or angle B then get the length of AF Also get angle ADB thus you should know how to get AD
