Find the Tangent Given the Point (0.8,0.6)

To find the ${\displaystyle \tan \left(\theta \right)}$ between the x-axis and the line between the points ${\displaystyle (0,0)}$ and ${\displaystyle (0.8,0.6)}$, draw the triangle between the three points ${\displaystyle (0,0)}$, ${\displaystyle (0.8,0)}$, and ${\displaystyle (0.8,0.6)}$.

${\displaystyle \tan \left(\theta \right)=\frac{\text{Opposite}}{\text{Adjacent}}}$ therefore ${\displaystyle \tan \left(\theta \right)=\frac{0.6}{0.8}}$.
