Problem

Dumpling the cat loves to play with little toys and then push them under the couch. Every week or so, Mom lifts up one side of the couch so Luke and Katie can pull all of the toys out.
Mom picked up the couch to an angle of 31, degree, but the kids still could not reach the toys. Then, she lifted it up another 15, degree, and the kids pulled out a bouncy ball, a foam dart, 3 rubber bands, and a Lego.
What was the measure of the total angle Mom lifted the couch?
