ANSWER:
The value of x is 16.49
STEP-BY-STEP EXPLANATION:
We can calculate the value of x by means of the tangent trignometric function, which is the following
[tex]\begin{gathered} \tan \theta=\frac{\text{opposite}}{\text{adjacent}} \\ \theta=70\text{\degree} \\ \text{opposite = x} \\ \text{adjacent = 6} \end{gathered}[/tex]Replacing and solving for x:
[tex]\begin{gathered} \tan 70=\frac{x}{6} \\ x=6\cdot\tan 70 \\ x=16.49 \end{gathered}[/tex]
