Answer:

14.4 m

Step-by-step explanation:

let the height of the tower from line of sight be x, then

tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{30}[/tex] ( multiply both sides by 30 )

30 × tan23° = x , thus

x ≈ 12.7 m

Total height of tower = 12.7 + 1.7 = 14.4 m ( to the nearest tenth )
