**Reiny**, Saturday, May 21, 2011 at 8:25pmmake a diagram, draw a horizontal line to the pole, let the top part of the pole be x,

then the bottom part of the pole is 60-x

call the horizontal distance to the pole = y

tan 18° = x/y

x = ytan18

tan 14 = (60-x)/y

60-x = ytan14

x = 60 - ytan14

ytan18 = 60-ytan14

ytan18 - ytan14 = 60

y(tan18 - tan14) = 60

y = 60/(tan18° - tan14°)

= ...

I will let you do the buttonpushing.
