I can only repeat it again and again: I wish i had more teachers like him. I can easily follow him although i'm not a native english speaker. Top teaching!

I love how you need to know this for foundation maths in England...

I swear AP mathematics is extremely difficult in America, far more difficult that higher maths in England. Am I wrong?

This is bringing back some memories from AMS 5.

MR WOO I LOVE YOUR LESSONS

[@EmileA239Noble4]

As far as I can tell, you could calculate it this way: Sin(gamma) = b / c | multiple with c Sin(gamma) * c = b | divide with Sin(gamma) c = b / sin(gamma) c = 8 / sin(45 degree) c = 11.31cm

[@derektruong6272]

Your answer is given to 2 decimal places, the question asks for an exact answer.

[@chessandmathguy]

If it's multiple choice then sure 8 root 2. But if it's free response, wouldn't a final answer of 8sin(45 degrees)/sin(30 degrees) cm be correct as well? I mean not all sine of angles come out to nice radicals. Sin 44 degrees for instance has no good way of rephrasing I think.

Still dude he is teaching them just basic sine rule. We taught that in class 9 or 10. And formally it is also in textbook of class 11.
