i am only on question 2 EDIT: On question 3 now but that's only because I skipped the rest of question 2 due to it's difficulty

it asked for the area of the parallelogram and i only got the area of the triangle. Forgot to times it by 2

God damn it demento y u hve to point that out' makin' me look like a fool

THANK THE LORD I FINALLY GET ANOTHER QUESTION RIGHT THATS A TOTAL OF 2 QUESTION CORRECT SO FAR.c um next question just ruined my joy what the how in the world do you do the next one?

Area = 1/2 x 10 x 7 x sin30 ???

Re: 2012 Year 9 &10 Mathematics Marathon lol my bad didn't read question properly

Re: 2012 Year 9 &10 Mathematics Marathon I meant using pythagoras to find the height so I can use the area (height x base) for the parallelogram

Re: 2012 Year 9 &10 Mathematics Marathon ok guise i got dis

Re: 2012 Year 9 &10 Mathematics Marathon for b part 2, do you use pythagoras

Re: 2012 Year 9 &10 Mathematics Marathon m8 i already got that question lolwat

Re: 2012 Year 9 &10 Mathematics Marathon i give up

Re: 2012 Year 9 &10 Mathematics Marathon oh my gosh this thing is so frustrating

Re: 2012 Year 9 &10 Mathematics Marathon lol my bad same shit

Re: 2012 Year 9 &10 Mathematics Marathon idgi So can I just replace the second line in my proof with "Angle BAC = Angle BDC (given)" and make it AAS lol

Re: 2012 Year 9 &10 Mathematics Marathon fuck you -_- Also, for question 2 b, is this right for the proofs? In Triangle BAC and CBD, Angle BDC = Angle CBA (alternate angles are equal in parallel lines) BA = DC (given) BC is common Therefore, Triangle BAC and CBD are congruent (SAS) ????

Re: 2012 Year 9 &10 Mathematics Marathon okay sweet FINALLY QUESTION 2 AFTER 1 HOUR...

Re: 2012 Year 9 &10 Mathematics Marathon I know that you're suppose to find the intersection points by solving it simultaneously but really? How the hell am I going to solve y = 2/x and y = x^2 - 4 simultaneously really

Re: 2012 Year 9 &10 Mathematics Marathon ... ... i'm still on question 1

Re: 2012 Year 9 &10 Mathematics Marathon I don't even put points in I sketch 2/x as if it were 1/x, 1000/x or any number over x and say that it's 2/x

Re: 2012 Year 9 &10 Mathematics Marathon Is it okay if I just sketch 2/x randomly and label it as 2/x because it has no intercepts and stuff so it doesn't matter? (lol) that's what i've been doing so far hahaha
