  1. sqrt[(6370+350)^2 -(6370)^2]
    = 2140 km

    The hypotenuse is 6720 and the radius (6370) from the center to the point of tangency is perpendicular to the earth's surface

  2. let that distance be x

    solve ...

    x^2 + 6370^2 = 6720^2

    ( I got 2140.44)

  3. Yeah so add 20 plus 11 and get 47 , that's the short way , because once you do that , you'll easily get 2140.5 , you welcome.
