I don't know how to solve for the measures of each angle but I can tell what type of angles each of these are. (a) obtuse angle, (b) not sure, (c) not sure, (d) The relationship between the angles BA and BE is that together they form a right angle. And #3, I cannot helps with. Very, sorry that I was not able to answer all of your question. Hope this helps!
