What you say makes no sense.

The problem is LITERALLY unsolvable if we can't assume that all the lines are straight.

The schematic was OF COURSE purposefully drawn in a way to make the viewer assume that the third angle of the left triangle is 90°, making the angle to it's right also be 90°, but the point of the exercise is to get the student to use ALL the given information instead of presuming right angles.

And NO, assuming all the lines are straight is NOT unreasonable, it is the only way that the problem could ever possibly have a solution.

I'd say that the shape on the left has what appears to be a little kink right near X, so one might infer that the shape on the left might be a quadrilateral. There are blatantly obvious vertices that are not labeled as such, so we can't assume that the not-quite-straight line is supposed to be straight since other angles are also not explicitly indicated as vertices...
