    This video is a life saver. I want to say you taught this in a much easier to understand way than my teacher did in a week. Granted, I didn't pay much attention on Sines, but I did with Cosines, and I now have a clear understanding of both. My teacher never mentioned anything about Cosines being used on SSS and SAS triangles. You have a really good way of teaching this stuff. Good job!

    Mario's explanations and examples are amazing. He makes learning the material so many times easier, and the fact that he's doing this for free and out of the good of his heart is amazingly gracious. He's the math teacher we all wanted, but didn't deserve. Someone give him a cinnabon

    • @CookiehsAndDreams
      @CookiehsAndDreams 3 года назад +8

      I might be a little late on this and I don't fully understand it either, but if you have the angles of the other two sides, you should be able to just subtract those two angles from 180, you should be able to get the missing angle. I might be wrong, but I hope I could help a little!
