**Henry**, Sunday, March 25, 2012 at 9:45pmWe form 2 rt triangles with a common ver. side.

tan27 = h/x.

Eq1: h = X*tan27 = 0.5095X.

tan24 = h/(X+1).

h = tan24*(x+1).

h = 0.4452(x+1).

h = 0.4452x + 0.4452.

0.5095x = 0.4452x + 0.4452.

0.5095x - 0.4452x = 0.4452.

0.0643x = 0.4452.

X = 0.4452 / 0.0643 = 6.92. Miles.

h = x*tan27 = 6.92*tan27 = 3.5 Miles.
