Find Angle DEA and Angle ADB
Date: 28 Apr 1995 00:28:32 -0400 From: Anonymous Subject: Geometry 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.

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! -K
