Suppose you live 3.6 miles from a hill. From your home you see a plane directly above the hill. Your angle of elevation to the plane is 11°. What is the plane’s altitude?

    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

    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
