Seems to be a lot of disagreement on the last answer
I'll put in my vote for n=20 (that's what I got)

well its wrong.You multiply by 4. The arc AC has 2 triangles there: AOB and BOC. The angle MOB = 39, which makes up for a half of ONE OF THE TRIANGLES. Which means there are 3 other halves left to account for. Therefore the angle AOC = 39*4.
(360-39*4 = 204 ---- (204/360)*2(8.5)*pi = 30.264 = 30.3 (3 s.f.))
[That's what I got anyway]

well maybe ur wrong.. unless somehow u knew the paper before.. STOP telling ppl ur wrong GODwell its wrong.
1744 I guessspeed of water
I got goosebumps when I saw the last questionsI was surprised at paper 42! It was one of the hardest papers I've seen (and I've done tons of past papers)
same here, I 360 by the angle above and then rounded it off!Me i got n=20
yes, when you subtract 1 from 20, you get 19 (the number of triangles where 19) as there was also a empty space left in the circle!yeah it was 19 triangle i agree but here's the trick they asked for the point if u remember i don't know how to explain it but they werent asking for the number of triangle i am almost 100% sure it is 20
ME!!!!!!!In the last question, who got n=20?
Hahahahaha! That was the easiest question! The rest of the paper was a pain in the ass!speed of water
you also got 2o right?only people who used their brains will understand this
what was your answer?Hahahahaha! That was the easiest question! The rest of the paper was a pain in the ass!
well u no wat at first i also did the same thing....bu while rechecking i realised they want the major AC not MN....so we had to multiply 39 by 4 and subtract it form 360.....and find the arc length.....this was the trap in this question and looks like you fell for it!!!well its wrong.
yeps AC major arc was 360-78! and i bet u fell for it too XD
Listen that was major arc MN when they were extended to touch the circumfernce of circle...and sometimes you may have to admit that u're wrong...just go with it......thats a sincere adviceyeps AC major arc was 360-78! and i bet u fell for it too XD
fine...then lets wait till the paper is uploaded....so we can know who is wrong...mayb i am wrong ...and btw....i am a GIRL!!no bro im sure about it... and i know i ddnt make that mistake
I did the samewell u no wat at first i also did the same thing....bu while rechecking i realised they want the major AC not MN....so we had to multiply 39 by 4 and subtract it form 360.....and find the arc length.....this was the trap in this question and looks like you fell for it!!!
No i am anti-bio.....wt abt u?nothing u giving bio?
sorry but ur gonna lose 3 or whatever marks it was.well u no wat at first i also did the same thing....bu while rechecking i realised they want the major AC not MN....so we had to multiply 39 by 4 and subtract it form 360.....and find the arc length.....this was the trap in this question and looks like you fell for it!!!
