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.
