BE=CD-37cm

BF=26cm

FC=14cm - Aug 14th 2006, 02:58 PMThePerfectHacker
Let EH represent the perpendicular line drawn from E to BC, i.e. the height. Now,

$\displaystyle \Delta EHC\sim \Delta OFC$

But, $\displaystyle OF=\frac{1}{2}EH$ (half the height).

Thus,

$\displaystyle \frac{OF}{EH}=\frac{1}{2}$.

Now use similar triangles,

$\displaystyle \frac{OF}{EH}=\frac{FC}{CH}$

Thus,

$\displaystyle \frac{FC}{CH}=\frac{1}{2}$

Thus,

$\displaystyle FC=\frac{1}{2}CH$

Thus,

$\displaystyle CH=2FC$

Thus,

$\displaystyle CH=2(14)=28$

Then,

$\displaystyle HF=CH-FC=14$

Then,

$\displaystyle BH+HF=26$

Thus,

$\displaystyle BH+14=26$

Thus,

$\displaystyle BH=12$

Finally Pythagorean theorem,

$\displaystyle BH^2+HE^2=BE^2$

Thus,

$\displaystyle (12)^2+HE^2=(37)^2$

Thus,

$\displaystyle 144+HE^2=1369$

Thus,

$\displaystyle HE^2=1225$

Thus,

$\displaystyle HE=\sqrt{1225}=35$ - Aug 14th 2006, 03:08 PMAHDDM

Thank you very much. This site pwns.

Pwns stands for Pawns, as in wins/awesome.
