Find the Exact Values of the Three Trigonometric Functions Sine $a = \frac { 4 } { 5 } , b = \frac { 3 } { 5 }$

Multiple Choice

Find the exact values of the three trigonometric functions sine, cosine, tangent of the real number t. $a = \frac { 4 } { 5 } , b = \frac { 3 } { 5 }$

A) $\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\\cos t = - \frac { 4 } { 5 } \\\tan t = - \frac { 3 } { 4 }\end{array}$
B) $\begin{array} { l } \sin t = \frac { 3 } { 5 } \\\cos t = - \frac { 3 } { 4 } \\\tan t = \frac { 4 } { 5 }\end{array}$
C) $\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\\cos t = - \frac { 3 } { 4 } \\\tan t = \frac { 4 } { 5 }\end{array}$
D) $\begin{array} { l } \sin t = \frac { 3 } { 4 } \\\cos t = \frac { 3 } { 5 } \\\tan t = \frac { 4 } { 5 }\end{array}$
E) $\begin{array} { l } \sin t = - \frac { 3 } { 5 } \\\cos t = - \frac { 4 } { 5 } \\\tan t = \frac { 3 } { 4 }\end{array}$
