The choice is tangent rule and the distance from the base to the tower is 3. 98 meters
The trigonometric ratio to use is
tan α = opposite side/ adjacent side
This is so because the angle 86° is facing the side of the distance from the top to the base
The choice is tangent rule
adjacent = x
Angle = 86°
Opposite side = 57
We have
tan 86° = 57/x
14. 300= 57/x
x = 57 ÷ 14.300
x = 3.98meters
Thus, the choice is tangent rule and the distance from the base to the tower is 3. 98 meters
