Let EH represent the perpendicular line drawn from E to BC, i.e. the height. Now,
$\Delta EHC\sim \Delta OFC$
But, $OF=\frac{1}{2}EH$ (half the height).
Thus,
$\frac{OF}{EH}=\frac{1}{2}$.
Now use similar triangles,
$\frac{OF}{EH}=\frac{FC}{CH}$
Thus,
$\frac{FC}{CH}=\frac{1}{2}$
Thus,
$FC=\frac{1}{2}CH$
Thus,
$CH=2FC$
Thus,
$CH=2(14)=28$
Then,
$HF=CH-FC=14$
Then,
$BH+HF=26$
Thus,
$BH+14=26$
Thus,
$BH=12$
Finally Pythagorean theorem,
$BH^2+HE^2=BE^2$
Thus,
$(12)^2+HE^2=(37)^2$
Thus,
$144+HE^2=1369$
Thus,
$HE^2=1225$
Thus,
$HE=\sqrt{1225}=35$

You are only 36, extremely young age for a physisit.

Thank you very much. This site pwns.

Pwns stands for Pawns, as in wins/awesome.
Example,
"ThePerfectHacker pawned the n00bish team with cheats in Battlefield 2"

Oookay, I'll have to look that one up in my chess-book. :)

Just for reference, "tyvm" is "thank you very much?" (Do you know I can actually type out the words in that faster than I can type tyvm?)

The sad thing is that some of us can now type it in $T_EX$ faster than it
takes to decipher the abreviation.
