• A) \(\begin{array} { l } \sin t = - \frac { 12 } { 13 } \\ \cos t = \frac { 5 } { 13 } \\ \tan t = \frac { 12 } { 5 } \end{array}\)
• B) \(\begin{array} { l } \sin t = \frac { 13 } { 5 } \\ \cos t = \frac { 13 } { 12 } \\ \tan t = \frac { 5 } { 12 } \end{array}\)
• C) \(\begin{array} { l } \sin t = \frac { 12 } { 13 } \\ \cos t = \frac { 12 } { 5 } \\ \tan t = \frac { 5 } { 13 } \end{array}\)
• D) \(\begin{array} { l } \sin t = \frac { 12 } { 5 } \\ \cos t = \frac { 5 } { 13 } \\ \tan t = \frac { 12 } { 13 } \end{array}\)
• E) \(\begin{array} { l } \sin t = - \frac { 12 } { 13 } \\ \cos t = \frac { 5 } { 13 } \\ \tan t = - \frac { 12 } { 5 } \end{array}\)
