An observer is 58 m from a tower. The angle of elevation to the top is 45°. Find the height of the tower.
Answer:
58.0
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 45° = height / 58. 3. Height = 58 * tan 45° = 58.0 m.
352

Answer:
280.59
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 60° = height / 162. 3. Height = 162 * tan 60° = 280.59 m.
353
An observer is 120 m from a tower. The angle of elevation to the top is 60°. Find the height of the tower.
Answer:
207.85
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 60° = height / 120. 3. Height = 120 * tan 60° = 207.85 m.
354
