Yet more Trig. (Mine shaft angle of inclination.)

  1. Dec 20, 2013 #1
    1. The problem statement, all variables and given/known data
    A mine shaft is 320 m in length and descends 74 meters. Find the angle of inclination.


    2. Relevant equations
    sin=opp/adj

    3. The attempt at a solution

    inverse sine=42/320
    inverse sine*.231=13.37 degrees.

    The answer seems conceivable.

    I take it the 42 is a typo. The answer looks right.
