make 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.
y= 60/(tan 18 + tan 14)
