find the length of line AD
... 1. Determine the angle at E:
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
