In traveling across flat land, you notice a mountain in front of you. Its angle of elevation to the peak is 3.5 degrees. After you drive 13 miles closer to the mountain, the angle of elevation is 9 degrees. Approximate the height of the mountain.

  • Math - ,


  • 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
