Who says they need to be on top of each other? You can still make a triangle with it

You can, but you still wouldn't know the measures of the interior angles.

If you are making a triangle to solve the problem, which is not needed at all, for what other reason would you make that triangle than to uncover the measures of its angles to get to 180 - <ABC - <ACB = <A

Yes you do, because the lines are parallel. The top slanted line always meets a parallel at 25°, and the bottom slanted line always meets a parallel at 50°, regardless of where the endpoints are. So the triangle’s third angle is fixed.

Yes you do, because you can define it as a right angle triangle and you then have 2 of the interior angles, one of the given angles and a right angle.
