Using Sine of angles to evaluate for x

The formula is,


sin\theta=(Opposite)/(Hypotenuse)

Given:


\begin{gathered} Opposite=x \\ Hypotenuse=19 \\ \theta=21^0 \end{gathered}

Therefore,


\begin{gathered} sin21^0=(x)/(19) \\ \therefore x=19* sin21^0 \end{gathered}

Simplify


x=6.80899\approx6.81\text{ \lparen2 decimal places\rparen}

Hence,


x=6.81
