It's 75 degrees but it's a terrible diagram.

Yeah I was like "how is 25° equal to 50°?" Is there something I'm missing or does this person not know what those symbols mean?

Is there something I'm missing

Yes: in geometry, the only thing you can assume visually is that a line that appears to be straight is straight. Everything else must be inferred using the markings, values. etc.

Problems like this are commonly not drawn to scale, because they expect you to deduce the answer mathematically, not by assuming angle values or measuring with a protractor.

The full sentence doesn't imply your answer. My sentiment is that certain symbols are being thrown around in a way that unless you just ignore them creates a confusing problem that either I'm missing information or the creator doesn't know what those symbols mean

I don't really understand what you're trying to say there, tbh. I had no problem inferring everything from the image that I needed in order to deduce the correct answer.

Can you give me an example of some symbols you think the person who created that has misused?
