well the line passing from one point through the triangle to the base of another side can be calculated using pythagoras theorem

12^2 - 6^2 = (x+y)^2

x+y = sqrt(108)

the gravity point (where all the internal lines meet) is always 2/3 from the apex or 1/3 from the base

therefore

y = (2/3)sqrt(108)

x = (1/3)sqrt(108) - March 30th 2008, 12:47 PMzachcumerThanks for the help!
Thanks for the help...have a nice day!

Here is another fun one!

Look at attached...@!@

The tick marks are 9...

Thanks

Best,

lol xD same thing just change all the 6 to 9 and all the 12 to 18 (Giggle)

What I have been getting is: (x + y)^2 + 81 = 18^2...am I right...if so...hmm

- March 30th 2008, 01:13 PMDanshader
yup thats right xD just continue the other steps

(i made a mistake above (Lipssealed) sorrie it should be 12^2 - 6^2 instead of adding them up) - March 30th 2008, 01:14 PMzachcumerCorrection!
18^2 - 9^2 = (x +y)^2

x + y = √(243) - March 30th 2008, 01:15 PMDanshader
nono o.o"

it is

18^2- 9^2 = (x+y)^2 - March 30th 2008, 01:22 PMzachcumer
got it!

Hey so the final answer is : .....one momento...

x = 1/3√(243)

y = 2/3√(243)

RIGHT?!?

Cool. Thanks.. - March 30th 2008, 01:24 PMDanshader
xD eres correcto bravo

Shank You Very Much!!!

- March 30th 2008, 01:27 PMzachcumerMore!! Yaya!!
Check dis out..dawg!

okay..look at attached! - March 30th 2008, 01:34 PMDanshader
lol they already given you the length xD

the answer is x = (1/3)(18)

y = (2/3)(18) - March 30th 2008, 01:42 PMzachcumer
Hey I need to find the area of THIS WHOLE TRIANGLE..

here is what I came up with:

36 + (2/3√(108) + 1/3√(108))^2 = 12^2

?
