Slide 12: I couldn't decide whether or not sin(B) was positive or negative (in the 2nd or 3rd quadrant). I think you need the additional information that B is obtuse. This is given in the textbook but missing from the slide. Thanks for these amazing resources!

I think there's a typo on slide 27, it should be asin(theta) + bcos(theta) but it is asin(theta) + bsin(theta) right now
