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 .

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?

Too lazy to type / copy / paste but if you do a search, you will find the answer.

Mean and SD is derived from the (statistics) population, ie those who take the exams.

Is anyone familiar with the marking criteria for math long answer qn? If the answer is correct, but the methods/ steps shown are entirely wrong, will there be any mark given?

Thank you![/quote]The statement is \" the angle is 90 degrees.\"
The given are : 70 degrees and 30 degrees angle. Based on Dd, you cant tell as whether you put in 90 degrees or 85 degrees, both are possible, in fact many possible answers..that is why, it is not possible to tell.

I got 92 degrees from using trapezium(360 degree) - the other sides.

OMG I JUST REALISED!
NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO :stompfeet: :gloomy: :stupid: :lightrod:[/quote]HI, I am also a student writing PSLE this year. For the part c on this question, I don't understand how the angle can be 85 degrees there bcos when i measured using my protractor, it was more than 90. So then how do we know that it is 85? Since both can be possible, true and false, my math teacher says that we should put NPTT.
