## Algebra 1: Common Core (15th Edition)

The question gives us the angle, which is found by $12+21 = 33$. The length of the base is 792. Using the tangent rule of $\frac{Opposite}{Base}$, we can set the equation up as $tan 33 = \frac{p}{792}$. To simplify the equation, we multiply both sides by 792 to get a new equation of $tan33 * 792 = p$. Solving for $tan33$, we get a value of 0.649. This value multiplied by 792 will return our answer, which is $514.3$.
