$\sin \theta=\dfrac{15}{17}$ $\cos \theta=\dfrac{8}{17}$ $\tan \theta=\dfrac{15}{8}$ $\csc \theta=\dfrac{17}{15}$ $\sec \theta=\dfrac{17}{8}$ $\cot \theta=\dfrac{8}{15}$

Work Step by Step

The Trigonometric Identities can be defined as: $\sin \theta=\dfrac{Opposite}{Hypotenuse}=\dfrac{15}{17}$ $\cos \theta=\dfrac{Adjacent}{Hypotenuse}=\dfrac{8}{17}$ $\tan \theta=\dfrac{Opposite}{Adjacent}=\dfrac{15}{8}$ $\csc \theta=\dfrac{Hypotenuse}{Opposite}=\dfrac{17}{15}$ $\sec \theta=\dfrac{Hypotenuse}{Adjacent}=\dfrac{17}{8}$ $\cot \theta=\dfrac{Adjacent}{Opposite}=\dfrac{8}{15}$
