An observer is 142 m from a tower. The angle of elevation to the top is 45°. Find the height of the tower.
Answer:
142.0
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 45° = height / 142. 3. Height = 142 * tan 45° = 142.0 m.
372
An observer is 156 m from a tower. The angle of elevation to the top is 60°. Find the height of the tower.
Answer:
270.2
Step-by-step solution: 1. Use tan θ = opposite/adjacent. 2. tan 60° = height / 156. 3. Height = 156 * tan 60° = 270.2 m.
373
