Answer: A

Step-by-step explanation:

I am not entirely sure, but the answer would most likely be A. Since the coordinates for the tops of the triangles are the same, I would assume that the bottom parts would be the same as well. This is probably not the correct answer, but it's my best attempt. I'm apologize in advance if it was not the answer you were looking for.

The third angle in the left triangle is 180-126-16 = 38 degrees

That's also the angle that with 16 and 3x  add to 180 degrees,

16 + 3x + 38 = 180

3x = 180 - 16 - 38 = 126

x = 126/3 = 42

Answer: C  x=42
