$\tan (30) = \frac{8}{x}$

Step 1

Subtract $\frac{8}{x}$ from both sides of the equation.

$\tan (30) - \frac{8}{x} = 0$

Step 2

The exact value of $\tan (30)$ is $\frac{\sqrt{3}}{3}$ .

$\frac{\sqrt{3}}{3} - \frac{8}{x} = 0$

Step 3

Set the denominator in $\frac{8}{x}$ equal to $0$ to find where the expression is undefined.

$x = 0$
