    Guys I'm really confused cause for the last question I got 185cm2 but the answer is 188cm2? Like wtf lol? Can anyone explain, cause I did cosine rule to get 'a' then used sin rule, and Pythagoras and area of triangle (1/2 bxh) and (1/2abSinC) then added them all up, plus I stored everything on my calculator, so I didn't round anything too early

    Do you think they will accept 185? If not how many marks do you reckon I'd get out of 6 cause I did everything everyone else did lol

    I'm just curious about how you implemented the sin rule? I did what you did with 1/2absinc, cos rule and Pythagoras, but I didn't use the sin rule at all.

    I think I used sine rule to get 'SinC' in 1/2abSinC?

    Dude I just realised my mistake...
    True I didn't need to use sine rule, but that's not relevant...
    For some reason in the exam, I thought 13/2 = 7.5; when really it's 6.5

    So from there my answer started going wrong.,.but there's still method marks for ecf so I will probably lose M1A1 but should hopefully get the rest, cause the rest of the working is otherwise right!

    Yeah the bottom line was 13 cm and the two lines on the left/right were 8cm and 12cm. The size of the angle between those two lines was 105.

    You'll lose a mark or two I'm afraid depending on how many marks it was worth.

    I feel the grade C and B boundary might be higher but the A/A* should drop a few marks...
