Everyone I spoke to got 69
i got 69 in the exam and it looks like it is 69, i used alternate segment twice, first one giving me the top angle on the isosceles then taking it away from 180 then dividing by 2 to give me base angle and then the 2nd time gave me the angle.

Same! How did you prove the surd questions
Do you mean the one that the answer if always multiple of 3?
I just expand it and finally got 6a+3a*2

And then i said all no. Multiply by 3 will be the multiple of 3 (idk actually haha)

Took a random value for a and just expanded and showed the answer was a multiple of 3
13. Judging by the difficulty of this paper and last year's paper in gonna say 60 Is an A
14. What was the probability for the 1 which was ( he wins 3 times )
How we had to do that ?

it was like (0.35) + (0.05 x 0.35) + (0.05 x 0.05 x 0.35)

which is = 0.35 + 0.017 + 0.000875

= 0.367875

thats correct but then you need to factorise it to 3a(2+a) because anything times by three is always a multiple of three
20. how about the drawing questikn?
