Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means misguided so the verb vocab version is to be misguided.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: If you are going to be misguided you're going to be mad (まど) about it, most likely. Nobody likes to be misguided, so imagine how mad you feel when you are.
