  • Math -

    a= 13 tan(3.5) h= the height of the mon.

    h= 13 tan(9)-a
    h=13 tan(9)-13tan(3.5)
    h=1.264 feet

  • PreCalc -

    you place the coefficient of the radical in the power. Then you divide by 13 and multiply by (tan(9)xtan(3.5)). Then you put the x into the equation to find the height of the mountain
