they add to 180
we know that they are x and 112
x+112=180
minus 112 both sides
x=68

answer is x=68 degrees

Solutions 

We know that a straight line is 180° and the angle given is 112°. To solve the problem you have to subtract 112° from 180°. 

180° - 112° = angle x

Angle x = 68° 

Check your work 

Let angle x = 68°. 

112° + 68° = 180° 

The answer is correct.
