For example consider this possible conversation: 「なんでそんなに汗びっしょりなの？」 "Why is/are [pronoun] so sweaty?" (this sentence can be talking about you, he, she, it, they, depending on context) 「１日中テニスをしていたんだから。」"(Because) [pronoun] was playing tennis all day" Here I shortened のだから into んだから, because that's a more conversational form (it's still the same thing). When you see だから or other particles at the end of a sentence that is being treated as complete, that means the rest of the sentence is already clear in context or the person wants you to infer.
