tan (40) = \frac{x}{10}

$\tan (40) = \frac{x}{10}$

Step 1

Rewrite the equation as

\frac{x}{10} = tan (40)

$\frac{x}{10} = \tan (40)$ .

\frac{x}{10} = tan (40)

$\frac{x}{10} = \tan (40)$

Step 2

Multiply both sides of the equation by

10

$10$ .

10 \frac{x}{10} = 10 tan (40)

$10 \frac{x}{10} = 10 \tan (40)$
