Kevin and Rob are standing on opposite sides of Edmonton's River Valley. In order to see a boat on the river, Kevin has to look down 32°, and Rob has to look down 38°. The width of the valley is 750m, and the boat is exactly between Kevin and Rob. How much higher is Rob than Kevin?

  • Math -

    If their heights are k and r, then
    k/375 = sin 32°
    r/375 = sin 38°

    So, the difference is

    r-k = 375(sin38°-sin32°)
