Technically there is a notation for parallel lines so you can't actually assume that, but I agree with everyone else that this would have been funnier if it added up to 180 degrees.
Btw. PSA to young folks, that notation looks like > on each line and some standardized tests will fucking get you on a technically with that shit, especially with the "it's impossible to know" answer being an option.
That's just what I was thinking. Do they swoosh the joke and just assume OP is an asshole?
