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!
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
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.
Can’t believe this channel isn’t bigger. It should be right up there with khan academy.

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?
Eddie Woo:
Given the way you do it, I guess that you, for sure, have to know 10x more than you teach us.
Have a Happy New Year 2021.
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
Your answer is given to 2 decimal places, the question asks for an exact answer.

This is bringing back some memories from AMS 5.
Thanks for helping me get a band 6 in adv maths :)
Triangle questions in A-Level maths are so annoying
@@randomdude2224 More often that not, drawing lines from the vertex to the centre of the circle will help.

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.
