    How do you do part b of question 1? I used the sine rule and got 6.36cm (3sf), is that correct?

    Any help will be appreciated

    I'm also doing GCSE and I'm not the best at Maths so I may also be wrong, but I also got 6.36cm.

    Here's a clue: What does bisect mean? It uses that word in the question.

    I got 6.35cm. Obviously I have made a minor calculation error, but our methods must have been similar.

    I did tan-1(18/6) to get x. Then bc it's bisecting DBC=45. I then added x and 45 and subtracted it from 180 to get BDC. Used the sine rule to get line BD hope that helps not really good at explanations
