So what I did was:
Found all the angles in a triangle
Vertically opposite angles are equal so in the middle triangle two of the angles are 96° and 42°
Find the last angle
180-(96+42)=180-138=42°
To find x
By using the parallel lines with 1 arrow we can use alternate interior angles to find x
So...
x=42°
Sorry it’s kinda confusing, there’s other ways to work it out as well, if you don’t understand feel free to let me know and I can try to explain a different way to solve
