Find the Tangent Given the Point (3,0)

To find the ${\displaystyle \tan \left(\theta \right)}$ between the x-axis and the line between the points ${\displaystyle (0,0)}$ and ${\displaystyle (3,0)}$, draw the triangle between the three points ${\displaystyle (0,0)}$, ${\displaystyle (3,0)}$, and ${\displaystyle (3,0)}$.

Opposite : ${\displaystyle 0}$

Adjacent : ${\displaystyle 3}$

${\displaystyle \tan \left(\theta \right)=\frac{\text{Opposite}}{\text{Adjacent}}}$ therefore ${\displaystyle \tan \left(\theta \right)=\frac{0}{3}}$.
