An observer is 138 m from a tower. The angle of elevation to the top is 60°. Find the height of the tower.
Answer:
239.02
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 60° = height / 138. 3. Height = 138 * tan 60° = 239.02 m.
392
An observer is 74 m from a tower. The angle of elevation to the top is 30°. Find the height of the tower.
Answer:
42.72
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 30° = height / 74. 3. Height = 74 * tan 30° = 42.72 m.
393
An observer is 204 m from a tower. The angle of elevation to the top is 60°. Find the height of the tower.
Answer:
353.34
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 60° = height / 204. 3. Height = 204 * tan 60° = 353.34 m.
394
