Question 893078
Distance on ground from point under the plane to the town for any angle of depression theta from the plane, d.


{{{h/d=tan(theta)}}}
{{{d/h=1/(tan(theta))}}}
{{{d=h/(tan(theta))}}}


Each distance d includes a portion in which is of no interest; instead you wan the DIFFERENCE between values.


Difference between the two towns:
{{{h/(tan(theta[2]))-h/(tan(theta[1]))}}}
{{{highlight(29000(1/(tan(58))-1/(tan(22)))(1/5280))}}}  MILES


Should be about 10.2 miles, but this was not checked.
