Answer:
165.8 ft (nearest tenth)
Step-by-step explanation:
We can use the tan trig ratio to calculate the height of the tower.
where:
= the angle
- O = the side opposite the angle
- A = the side adjacent the angle
From inspection of the diagram:
- O = height of tower (let's call this h)
- A = 220 ft
Substituting these values into the trig tan ratio:
Multiply both sides by 220:
Therefore, the height of the tower is 165.8 ft (nearest tenth)
