Question

I have to find the value of x but I need guidance

Answer 1

Using Sine of angles to solve for x

`sin\theta=(Opposite)/(Hypotenuse)`

Given:

`\begin{gathered} \theta=45^0 \\ Opposite=x \\ Hypotenuse=9 \end{gathered}`

Therefore,

`\begin{gathered} sin45^0=(x)/(9) \\ x=9sin45^0=(9√(2))/(2) \end{gathered}`

Hence,

`x=(9√(2))/(2)\text{ \lparen Option 2\rparen}`
