    Ahaha easier than square rooting rubbish numbers
    Square root of 225 is 15 over square root of 4 which is 2 so +-15/2, not too bad, I have no idea why you times 225 by 4 😂😂

    My teacher made a mark scheme. Only one i got wrong was the tanABC; I used the C co-ordinates instead of D co-ordinates so didn't get right answer :/ got all of the maths right though so it's just a matter of if i get ECF. If I get 0 for that question i end up with 70/75.

    How did you find it?

    What's ECF? And dropped 1 on q1 due to not simplifying, I had root 20 over 90 though, dropped 2 on 6b for not finding a correctly, and may have dropped 1 on 10 for not putting meteres next to L=80 so about 71/75, I always allow for silly mistakes so 68 worst case

    Good stuff. ECF is error carried forward meaning if you do something wrong at the start of a question then you only lose that mark if you do the rest of the question correctly just using the wrong number.

    Had to find tanABC but you need to use triangle ABD instead of ABC because ABC is not right angle but ABD is. tanABD and tan ABC would have been the same angle I imagine. The answer was 1/2.

    I did same as you on it!
