Step-by-step explanation:
first you have to find the value of X. So you take both expressions and make them equal to 180 degrees. Then you solve for X. Once you do that X should equal 30. Then in place of X plug in 30 and solve. it should look like this (3(30)+22). The answer is 112 degrees.
You could of also looked at your angle and saw it was an obtuse angle. The only answer that was obtuse was 112 degrees.
I HOPE THIS HELPS!!!
