Good responses. Like Brad said, if you're "looking down" 18 degrees the adjacent angle is 72 degrees. Just be careful with the wording.

Draw a right triangle. The height is 60 ft, and the distance to be found is x.
x/60 = cot(18)
So, x = 60cot(18) = 60/tan(18) = 184.66 ft <==Answer
Hey Charles!
Looking down 90 degrees is looking straight down at one's burning feet.
60'
18deg << x >>
Tangent is opposite / adjacent or tower height / fire distance.
tan () = 60' / x
x = 60' / tan (18deg * 1 radian / 60deg) = 60' / tan (0.3 radians)
tan (0.3rad) happens to be about 0.3
x = 60' / 0.3 = 600' / 3 or about 200 ft away. Best wishes, sir.
