You’ll be in trouble after making dad mad.
Remember how you learned that 怒る means "to get angry?" Well this is when someone else gets angry and it's because YOU made them angry. It means "to anger someone."
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You learned this reading when you learned 怒る, so you should know this one too!
