Leg xy is where? Can you draw a picture? What's the height of the triangle?
it doesnt give me one i can try and draw one
\[A={1 \over 2}bh\] |dw:1354695650945:dw|

thats what it gives me
XY is on the bottom by the way forgot to add all that
|dw:1354695885781:dw|
no it is not. all it gives me is the area which is 36cm2
i want to say its 12 but not sure
since 36 is a perfect square.\[ \frac{ 1 }{ 2}(12)(6)=36cm^{2}\]
the base has to be 12
thats what im thinking
it gives me 5 different answers to pick from 6,9,12,18,24
No. \[(0.5)(24)(3)=36\]
so your saying 24 would be the length of leg xy?
@winterfez, that's incorrect, since 72 = 36x2 = 9x8= 18x4 and so on.. , many possibilities , i think phoenixfire leads him on the right track, need more info on this to solve.
well for this question you need to know either the height or the base
Could be a lot of different numbers. You're missing information.
i can take a picture of the diagram on my cell and upload it for you guys to see the diagram given to me
\[\frac{ 1 }{ 2}bh=36cm ^{2}\] I don't think you can find from this equation. Like PhoenixFire point out you need to know 1 more information for either base or height
give me a few i will upload a photo with everything given to me
that is what they have given me to work with
Leg XY is twice as long as YZ. That's the info we needed. Let b=XY and h=2b \[A={1 \over 2}2b^2=b^2\]\[\sqrt{36}=b=6\] Your leg XY=6 and YZ=12
phoenixfire, you got the other way around :) XY is twice as long as YZ :)
sorry bout that. my bad. this is my first time using this site. i thought i mentioned it. but thank you very much PhoenixFire, tamotan, and winterfez.
so the length of leg xy is 24?
I see. b=2h h=YZ \[A={1 \over 2}2h^2=h^2\]\[h=\sqrt{36}=6\] \[b=2h=2(6)=12\] XY = 12
there :)
My bad for that mistake. haha, Thanks @tamtoan
alright so its 12 like i thought lol:) i was confused. normally im good at math. but missing class and then getting this confused me
np phoenixfire :) i made mistakes all the time :) sometimes it's too easy that we are careless, anyway, good night all, bed time for me :)
thank you both for helping me. i did become fans and i think gave a medal? but thanks alot!!!
np :) Good Luck
thank you
