**Henry**, Monday, September 3, 2012 at 9:22pmDraw 2 rt triangles witha common ver. side.

h = Y = Ver. side.

1.1km+X = Hor. side.

X = dist. from hyp. of smaller triangle to base of tower.

tan6 = h/(1.1+X).

h = (1.1+X)tan6.

tan13 = h/X

h = X*tan13.

h = (1.1+X)tan6 = X*tan13

(1.1+X)tan6 = X*tan13

1.1*tan6+X*tan6 = X*tan13

X*tan6-X*tan13 = -1.1*tan6

0.1051x-0.2309x = -0.1156

-0.12577x = -0.1156

X = 0.92 km.

h = X*tan13 = 0.212 km. = 212 m.
