a worker walked 8ft. upa ramp and was 3ft. above ground level. If he walkes an additional 12ft. up the ramp,how many ft. will he be from the ground?

  • geometery -

    one could say

    8/3 = 12/height

    h(8/3) = 12

    h = (12x3)/8

    h = 4.5

    or use trigonometry and say

    sinX= 3/8

    X = (1/sin)3/8

    X = 22.02 which is the angle of the incline


    sin(22.02) = h/12

    12sin(22.02) = 4.5
