What is misplaced dangling Working extra hours last week, my salary dramatically increased
The example sentence you provided does not make sense as it is written. It combines a dangling modifier and a misplaced modifier in one sentence.
A misplaced modifier occurs when a word or phrase is placed too far away from the word it modifies, creating confusion or altering the intended meaning. In this case, the modifier "Working extra hours last week" is placed at the beginning of the sentence, but it is not clear what it is intended to modify.
A dangling modifier occurs when the word or phrase it is intended to modify is missing or unclear. In this case, it is unclear what the phrase "my salary dramatically increased" is meant to modify.
A revised and clearer sentence could be: "By working extra hours last week, I was able to dramatically increase my salary."
