actually can first assume that the angle is ninety degrees as perpendicular so there will be a right angle. then use the other angles to find out whether it adds up to 180 degrees ( as question says it’s a straight line ). my friend did that and she got 180 degrees in the end so i think it’s true.

Yes my Ds also try that . He was sad that didn't check other nos and got this part wrong .
He told me if u assume the angle to be 85 degree still work out to be 180 .

Was reading and noticed later why you didnt think it was possible. The above is “4 A” and “3 stars 1 A”.

Ah, ok... I misread too.

Not “too”.
I didnt misread it.
I was just wondering why you said it was not possible, when I thought it was very possible (even started to question my own understanding of t score).....until much later than i realised cos you thought it was 4 stars.[/quote]The \"too\" was with reference to Floppy...
After I confused the whole issue, he also salah Liao.

Was there a question about whole figure painted but then how many cubes did not have paint on any of its faces ?
( Not sure the question structure )

I got 92 degrees from using trapezium(360 degree) - the other sides.[/quote]OMG I JUST REALISED!

Mine got 10 too

Hi can I know how to calculate T score? I know raw marks is your own 4 subject aggregate marks. Then how is 'mean’and ‘standard deviation’ derives from? So is it better to have ‘tough’ papers year so that the mean/std deviation is lower/higher? How does it work?

so sad now :sad:
