Hi, I just have three question and I'm wondering how to solve them.(adsbygoogle = window.adsbygoogle || []).push({});

The first one is a sets question and it is literally infuriating trying to even contemplate it. I've asked many other people how to solve and no one knows how. I was hoping there would be a few geniuses that solve it here

The other 2 are just trig questions. I have a feeling at the back of my head that I knew how to solve them, but that's it.
