Answer:
34
Step-by-step explanation:
First you see that 112* in a straight line? The supplementary angle to that 112 degree is 180-112=68
Then you can tell that the triangle on the right has 2 angles 38 degrees and 40 degrees. So, the remaining angle is 180-78=102 degrees.
The left triangle with x + 68 + 78 = 180
Therefore angle x is 34
