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