Given:
The figure of a right angle triangle.
To find:
The length of the line segment AC.
Solution:
In a right angle triangle,
![\tan \theta=\dfrac{Opposite}{Adjacent}](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%3D%5Cdfrac%7BOpposite%7D%7BAdjacent%7D)
In the given right triangle ABC,
![\tan (A)=\dfrac{BC}{AC}](https://tex.z-dn.net/?f=%5Ctan%20%28A%29%3D%5Cdfrac%7BBC%7D%7BAC%7D)
![\tan (55^\circ)=\dfrac{BC}{AC}](https://tex.z-dn.net/?f=%5Ctan%20%2855%5E%5Ccirc%29%3D%5Cdfrac%7BBC%7D%7BAC%7D)
![\tan (55^\circ)=\dfrac{15}{AC}](https://tex.z-dn.net/?f=%5Ctan%20%2855%5E%5Ccirc%29%3D%5Cdfrac%7B15%7D%7BAC%7D)
![AC=\dfrac{15}{\tan (55^\circ)}](https://tex.z-dn.net/?f=AC%3D%5Cdfrac%7B15%7D%7B%5Ctan%20%2855%5E%5Ccirc%29%7D)
On further simplification, we get
![AC=\dfrac{15}{1.428148}](https://tex.z-dn.net/?f=AC%3D%5Cdfrac%7B15%7D%7B1.428148%7D)
![AC=10.503113](https://tex.z-dn.net/?f=AC%3D10.503113)
![AC\approx 10.5](https://tex.z-dn.net/?f=AC%5Capprox%2010.5)
The length of side AC is equal to 10.5 m .
Therefore, the correct option is A.
