      Nah, the imagery tricks you. 180 degrees to a line. 180 degrees inside a triangle.

      So you can gather the inside unlabeled angle on the triangle on the left is only 80 degrees: (180-[60+40])

      So you then know it’s 100 on the right side of that +35 leaves you with 45 degrees left for the top of the right one.

      180-45=. 135 degrees

        Also if you add up all visible angles you get 135, so I’m sold on that alone. No no no, I won’t hear any rebuttals.

        Oh that’s just a cheap trick. You are right, it’s 80 degrees despite looking like 90 degrees.

        You are right that is 80° so the value of x will be 135°
