        Oh shit you’re right. The left triangles unmarked angle is 80, meaning the right triangles internal angles are 100, 35, and 45. This means X is 135

        Even if it was a right angle, I think a second assumption is that the top left and bottom lines are equal length, which is also not stated.

        I think there’s just not enough information in this picture to calculate the angle, and it can only be determined by measuring. But the image also does not specify that it is drawn to scale.
