hello can you help me solve this plane trigonometry problem please and thank you for your time

Question:
Given the triangle
Find the value of x
Answer:
We know, because of the definition of trigonometric functions, that
[tex]\sin 45=\frac{9.9}{x}[/tex]We then have to clear x from this equation
[tex]\begin{gathered} \sin 45=\frac{9.9}{x}\rightarrow x\sin 45=9.9\rightarrow x=\frac{9.9}{\sin 45} \\ \text{Therefore,} \\ x=14ft \end{gathered}[/tex]
