Translation:You are angry
Mad and angry are synonyms. Can an alternative sentence be added as a possible correct answer?
You are angry/mad. You have gotten mad. You are pissed - they should work too, since they all mean the same thing.
Yeah, there are a lot of possible answers that need to be added to this course. Just press the report button.
(Outside of North America, "mad" is more or less synonymous with "crazy", at least until Americanisation fully takes hold, but yeah, it should definitely be accepted as a correct answer.)
