1. The last question was
....3
3X +6X -2 =0 work out x so it can't be degrees but apart from that I agree

Sector Q.
Do you by any chance remember what question this was?
3. Who else got 108 or 105 can;t remember for the polygon question?
4. 1b can also be 9/20
5. Why was the pentagon question 144? I got 108
6. (Original post by polarising)
Does anyone remember their answer for...22, I think? Making y the subject?

I forgot what the numbers were but I think I got (5b - x)² = y. Not sure whether that's even near the realm of correct but rearranging questions are always hit-and-miss for me.
I got 5b^2-x im not sure though yours is probably right though

7. Does anyone have a photocopy of the paper with answers??
8. I got -2.29 and 0.29
9. Hated that papwr so much but looking at the markscheme I think I've done okay?? Hopefully they'll lower the grade boundaries because last year was like
99 - B
125 - A
And 150 something for an A*
10. 21. 144 degrees

Yes! Guessed the **** out of that one!

I got something like that. I didn't put brackets though.
14. Guys for the trigonometry and Pythagoras question with triangles where you must find the missing angle the answer was 30.1° but I misread and got 30° as the answer. What's the max number of marks I could get?? I think I did everything else right...I used tan^-1 and then divided the side lengths I hope that's right????

I put brackets around the whole thing so it didn't imply that I was only squaring the x on the left side and not the whole equation.
18. You'll get an A.
19. (Original post by rayestar)
I'm pretty sure it was three bars
20. (Original post by Pro4TLZZ)
can it be 45%
I'm not too sure, if it was 2 marker I imagine you'll get at least 1 mark though.
