imagine...it's a right triangle....your house to the hill is adjacent, down hill to the plane is Opposite or the altitude...
so so tan (11) = opp/ adj = opp/ 3.6 => Opp = tan(11 degree) x 3.6

lolwut? but i guess if it makes logical sense....too bad the plane isnt
gonna make it too far over the hill if its on a negative slope haha.

But i say the question is wrong...
if the plane is seen on top of a hill from your home it doesn't mean it is exactly on top of hill

a_kaffash, you're wrong, the angle of elevation does not mean the plane will be on top of the hill, so the answer is .7 miles

you gotta be landing, prepin for bailout, or a really horrible, paraplegic down syndrome pilot to be that low to the ground. or at least have a legit reason hahahah.
