What did everyone get for the pentagon question?
144 degrees
2. I got that aswell!
3. (Original post by Benb2000)
I got 80.4 but don think it's right
I got 80.4 for the last question too!
4. For question 23, will you get 2 marks for 3-x/(x-3)(3x+4)?
Fully simplified it becomes -1/3x+4 rigth?

Ugh I got 30.0cm because I rounded the answer to 1 d.p for the Pythagorus theorem one.
don't worry you might still get all the marks, or at least you'll only lose 1 mark max probably
7. Non calc went better tbh
8. (Original post by student2607)
Yeah that's what I got too , seems to be a few different answers people got though so not sure if it's right
Yeah apparently, we worked out the wrong angle.
What about that trig one? I got like 30 point something
9. I think i got about 45 ish marks on both papers but thats probably going to be like 40. I REALLY need a C is that ok?
10. Who wants me back?
11. (Original post by FreakinYAY)
F*ck yeah got 80.1 without having a clue on what tf i was doing
Was the last one 80.1 ?
12. I thought the last one was 80.1? I probably did it wrong because I somehow managed to manipulate the sine rule instead of using the cosine rule...
13. (Original post by thomas-cowley)
Oh f**k, I got 47.5! How did you get that? I used 1/2absinc, cosine rule and then sine rule - and triple checked it
I got that!!!

Can't even remember what I got for that. Lol. Where do you think the grade boundary for an A will be this year ?

Working back from 1/2absinC
Yeah that's what I did too
17. Anyone get 20.7 for the triangle one
18. (Original post by sahra30013)
What? I got 80.4 but used cousins twice. Is that all right?
yeah you could do that because you found all 3 lengths

1. Order numbers correctly and include a key
b) 0.45
2a. 30abc
b.
c. x^2-3x

23. (3-x)/(x-3)(3x+4)
24. 2x/(x+1)(x-1)
25. 80.4
Woouldnt 23 be 3x+4 because you cancel 3-x and x-3 out??

For question 23, will you get 2 marks for 3-x/(x-3)(3x+4)?
Fully simplified it becomes -1/3x+4 rigth?
The original fraction was 3-x/3x^2 -5x -12, which factorises to 3-x/(3-x)(-3x-4). The 3-x is cancelled out and the answer is 1/-3x-4.
