A forest ranger in a 120ft observation tower sees a fire. The angle of depression to the fire is 3.5. What is the horizontal distance between the tower and the fire
Answered by Reiny
horizontal distance --- x
I see it as:
tan 3.5° = 120/x
x = 120/tan3.5 = appr 1962 ft

most likely add 3.5 and 120 then divide by 120? From my experience, i think that's what you do. Glad to be of hellp
