Answer:
10.99 m
Step-by-step explanation:
✍️What we are basically asked to solve here is to find the distance between C and D.
To find CD, find the length of BC, and BD. Their difference will give us CD.
Thus, BC - BD = CD.
✍️Finding BC using trigonometric ratio formula:
![\theta = 30 + 10 = 40](https://tex.z-dn.net/?f=%20%5Ctheta%20%3D%2030%20%2B%2010%20%3D%2040%20)
Opposite side = BC = ??
Adjacent side = 42 m
Thus:
![tan(\theta) = \frac{opposite}{adjacent}](https://tex.z-dn.net/?f=%20tan%28%5Ctheta%29%20%3D%20%5Cfrac%7Bopposite%7D%7Badjacent%7D%20)
Plug in the values
![tan(40) = \frac{BC}{42}](https://tex.z-dn.net/?f=%20tan%2840%29%20%3D%20%5Cfrac%7BBC%7D%7B42%7D%20)
Multiply both sides by 42
![tan(40) \times 42 = \frac{BC}{42} \times 42](https://tex.z-dn.net/?f=%20tan%2840%29%20%5Ctimes%2042%20%3D%20%5Cfrac%7BBC%7D%7B42%7D%20%5Ctimes%2042%20)
![35.24 = BC](https://tex.z-dn.net/?f=%2035.24%20%3D%20BC%20)
BC = 35.24 m
✍️Finding BD using trigonometric ratio formula:
![\theta = 30](https://tex.z-dn.net/?f=%20%5Ctheta%20%3D%2030%20)
Opposite side = BD = ??
Adjacent side = 42 m
Thus:
![tan(\theta) = \frac{opposite}{adjacent}](https://tex.z-dn.net/?f=%20tan%28%5Ctheta%29%20%3D%20%5Cfrac%7Bopposite%7D%7Badjacent%7D%20)
Plug in the values
![tan(30) = \frac{BD}{42}](https://tex.z-dn.net/?f=%20tan%2830%29%20%3D%20%5Cfrac%7BBD%7D%7B42%7D%20)
Multiply both sides by 42
![tan(30) \times 42 = \frac{BD}{42} \times 42](https://tex.z-dn.net/?f=%20tan%2830%29%20%5Ctimes%2042%20%3D%20%5Cfrac%7BBD%7D%7B42%7D%20%5Ctimes%2042%20)
![24.25 = BD](https://tex.z-dn.net/?f=%2024.25%20%3D%20BD%20)
BD = 24.25 m
✍️How much below the top of the tower is the shorter one attached:
Thus,
BC - BD = CD
35.24 m - 24.25 m = 10.99 m
