Answer 2

Answer:

14.4 m

Step-by-step explanation:

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

tan23° = $\frac{opposite}{adjacent}$ = $\frac{x}{30}$ ( 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 )
