Can any of you /sci/entists help me out with how you'd go about solving this?

does redrawing it as pic related help OP?

No, I'm pretty much on lost on this. Our prof threw this on our E&M practice exam, saying it's a voltage divider, which is something we've never discussed and is only mentioned in our textbook in a practice problem. Not really sure about the analysis of it.

Yeah but how'd you arrive at this? I.e. what is the logic

it is a voltage divider. which is babby level circuits.

suggest some self study as the course seems to expect you to know babby level things.

just ohms law.

hah i appreciate the suggestion, but naw. i'm in introuctory E&M which is by definition babby level. Once I'm done with this class I will likely never deal with circuits again, ever, so I don't really care to self-study. I just know there are lots of physics majors on /sci/ who may be able to offer some help. Just want to know the process of solving these rudimentary voltage divider problems.

that's me. suggest you read the fucking internet

It's a simple voltage divider. All "R" are the same resistance. The resistor that connects to point "A" does not factor into the equation because an "ideal voltmeter" is a meter that has infinite resistance and doesn't load the circuit.
