There is nothing in the image that suggests that the bottom of both triangles forms a straight line.

Except for the part where it's a single straight line segment, as depicted in the image. Showing the complimentary angles as an unlabeled approximately right angle is within convention. Showing a pair of line segments that do not form a straight line as a straight line is not.

Exactly.

Add to this that x is literally impossible to calculate if conventions are not assumed, and absolutely possible to calculate if conventions are followed. Assuming the conventions won't hold is an irrational position.
