An observer is 196 m from a tower. The angle of elevation to the top is 45°. Find the height of the tower.
Answer:
196.0
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 45° = height / 196. 3. Height = 196 * tan 45° = 196.0 m.
402
An observer is 102 m from a tower. The angle of elevation to the top is 60°. Find the height of the tower.
Answer:
176.67
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 60° = height / 102. 3. Height = 102 * tan 60° = 176.67 m.
403
An observer is 220 m from a tower. The angle of elevation to the top is 45°. Find the height of the tower.
Answer:
220.0
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 45° = height / 220. 3. Height = 220 * tan 45° = 220.0 m.
404
An observer is 72 m from a tower. The angle of elevation to the top is 60°. Find the height of the tower.
Answer:
124.71
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 60° = height / 72. 3. Height = 72 * tan 60° = 124.71 m.
405

Answer:
91.22
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 30° = height / 158. 3. Height = 158 * tan 30° = 91.22 m.
406
An observer is 86 m from a tower. The angle of elevation to the top is 30°. Find the height of the tower.
Answer:
49.65
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 30° = height / 86. 3. Height = 86 * tan 30° = 49.65 m.
407
