Given: Line Ab is parallel to line DC, measure of arc CB =62, 
       measure of angle DAb=104.

Find the measure of angle DEA and the measure of angle ADB, 
and WHY

Thanks a lot.

Hello there!

Here's a hint that should get you started, and please write back if 
you're still stuck.  You said that arc CB is 62 degrees, so look at 
angle CDB. Since it subtends arc CB, it has measure 31 degrees.  See 
if this helps you (you can add and subtract angles until you find 
something interesting; also think about alternate interior angles), 
and write back if you're still stuck.  Good luck!
