A person in a 60ft tall tower is looking down 18 degrees at a fire how far away is the fire from the person
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
Looking down 90 degrees is looking straight down at one's burning feet.
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.
