The tangent of an angle is equal to the ratio of the opposite side to the adjacent side.

Substitute the name of each side into the definition of the tangent function.

Set up the equation to solve for the opposite side, in this case <math><mstyle displaystyle="true"><mi>a</mi></mstyle></math> .

Substitute the values of each variable into the formula for tangent.

Factor <math><mstyle displaystyle="true"><mn>3</mn></mstyle></math> out of <math><mstyle displaystyle="true"><mn>12</mn></mstyle></math> .

Cancel the common factor.

Rewrite the expression.
