[tex]\begin{gathered} \csc (\theta)=\frac{hypotenuse}{opposite}=\frac{9}{4} \\ \end{gathered}[/tex]
The tangent function is given by:
[tex]\tan (\theta)=\frac{opposite}{adjacent}=-\frac{4}{\sqrt[]{65}}[/tex]
And the cosine function is:
[tex]\cos (\theta)=\frac{adjacent}{hypotenuse}=-\frac{\sqrt[]{65}}{9}[/tex]
