Question

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

Answer 1

Question:

Given the triangle

Find the value of x

Answer:

We know, because of the definition of trigonometric functions, that

`\sin 45=(9.9)/(x)`

We then have to clear x from this equation

`\begin{gathered} \sin 45=(9.9)/(x)\rightarrow x\sin 45=9.9\rightarrow x=(9.9)/(\sin 45) \\ \text{Therefore,} \\ x=14ft \end{gathered}`
