Limit problem

  1. May 16, 2010 #1
    1. The problem statement, all variables and given/known data

    A hiker is at the base of a mountain and can get the horizantal distance between himself and the peak through GPS device:750 m. And suppose we know the actual measurements: It's a right triangle with an opposite= 750 tan (pi/6) = 433 m , an adjacent= 750 m, and a hypotenuse= 866.
    How accurate does the hiker need to measure Pi/6 in order to approximate the height of the peak within: +_ 20 m of accuracy?
    +_10 m of accuracy?

    2. Relevant equations

    3. The attempt at a solution
    -20<750 tan((pi/6)+E= epsilon)<20
    =>,43020< E
    is this how to solve it or my approach isn't correct?
