Are you doing Apex Geometry? I did it. Maybe I can help you out.

Don't take my word for it, but from what I remember about proofs, the answer would be A. They only give you one angle, after all. The triangles are right triangles and there is a theorem that could support my thesis, but I unfortunately no longer have access to the Apex textbook. I'm going to infer you already have the answer to this. But if you don't, good luck! Message me and I'll try to help!

Also, today might be your last day to complete the course. I'm finishing Pre-Calc Semester B today. You might be screwed if you don't fix this quick!
