    Correction - at 18:10 the final answer should be 53.4 not 53.5 🤦🏼‍♂️ no idea what I was looking at when writing that! - I’m only human!!

    GREAT LECTURES! Many thanks. Question: When using the Sine Rule a/SinA = b/SinB = c/SinC, is it OK to use d/SinD in your calculations. For example, I've labeled the triangle points A, B, C, D, etc., where D is an angle and d is an opposite side I want to use. The labelling just matches up, without having to re-allocate letters. Thanks in advance :)

      No it's 13.3 because its rounded at 3 significant figures , we rounded this to 13.3 because we got 13.34... , the only time we would round this to 13.4 would be if we got 13.35 , 13.36 13.37 ,13.38 or 13.39 ect ect , I hope that makes sense
