Find XY if WX = 1/3(XY) - Sep 27th 2007, 07:41 PMJhevon
No big deal here:

$\displaystyle WX = x + 2$, $\displaystyle XY = 5x + 2$

since $\displaystyle WX = \frac 13 XY$, we have:

$\displaystyle x + 2 = \frac 13 (5x + 2)$

now solve for $\displaystyle x$, and plug that value into the formula for $\displaystyle XY$ to find its length

this is my 39:):)th post!!!
