It has been a while since i have done trig and was looking to brush up. @ around 8:08 - 8:50, you got approxametly 50.8 degrees. I got around 42 degrees. This comes to A = Cos^1(-283/-384) which = aprox .7422 rad or 42.5 degrees. Am I wrong?

That is just blind memorization. Whenever I need to use cosine law to find the third side of a triangle opposite to an angle (Say A) I think of it more as a 'Find the hypotenuse ' problem except the hypotenuse is opposite to the angle A instead of 90°. This makes more sense to me and I can setup the problem correctly without any doubt.

"In triangle ABC, which is right-angled at B, angles A and C are both 45 degrees. If the lengths of sides AB and BC are both 2 cm, and AC (the hypotenuse) is \(2\sqrt{2}\) cm, I tried applying the sine rule. However, I'm confused because when I calculate \(\sin 90^\circ\) as \( \frac{\text{AB}}{\text{AC}} = \frac{2}{2\sqrt{2}}\), it doesn't equal 1 as expected. Could you please explain why this happens and how to correctly apply the trigonometric functions in this scenario?"

Must Know #1: I'd have simply said that because lines BC and DE are parallel, just know that BC / DE (which is 10 /4) would tell me the ratio (or the multiplier to use). So, 10 / 4 is 2.5, that's the multiplier to use on line DA (which is 6) to work out the length of line BA. So, 6x2.5 = 15. We know the long line DA is x +6 , and we know the length is 15, so x = 15-6, which is 9. It takes longer to explain it to actually do it as you can do it in literally seconds!
