than move 4 feet than total distance is 22 feet
According to trigonometry rule make 30 degree angle
![tan\left ( 30\ \right )^{o}=\frac{p}{b}](https://tex.z-dn.net/?f=tan%5Cleft%20%28%2030%5C%20%5Cright%20%29%5E%7Bo%7D%3D%5Cfrac%7Bp%7D%7Bb%7D)
![\left ( \frac{1}{\sqrt{3}} \right )=\left ( \frac{x}{18+4} \right )](https://tex.z-dn.net/?f=%5Cleft%20%28%20%5Cfrac%7B1%7D%7B%5Csqrt%7B3%7D%7D%20%5Cright%20%29%3D%5Cleft%20%28%20%5Cfrac%7Bx%7D%7B18%2B4%7D%20%5Cright%20%29)
or
![x\sqrt{3}=22](https://tex.z-dn.net/?f=x%5Csqrt%7B3%7D%3D22)
than
![x=\frac{22}{\sqrt{3}}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B22%7D%7B%5Csqrt%7B3%7D%7D)
