Determine the Exact Values of the Three Trigonometric Functions Csc $\theta$

Determine the exact values of the three trigonometric functions csc, sec, and cot of the angle $\theta$ .
Where a = 15 and b = 8.

A) csc $\theta$ = - $\frac { 17 } { 8 }$ sec $\theta$ = - $\frac { 17 } { 15 }$ cot $\theta$ = $\frac { 15 } { 8 }$
B) csc $\theta$ = - $\frac { 17 } { 8 }$ sec $\theta$ = - $\frac { 15 } { 8 }$ cot $\theta$ = - $\frac { 17 } { 15 }$
C) csc $\theta$ = - $\frac { 17 } { 8 }$ sec $\theta$ = - $\frac { 17 } { 15 }$ cot $\theta$ = - $\frac { 17 } { 8 }$
D) csc $\theta$ = - $\frac { 15 } { 8 }$ sec $\theta$ = - $\frac { 17 } { 15 }$ cot $\theta$ = - $\frac { 17 } { 8 }$
E) csc $\theta$ = - $\frac { 17 } { 15 }$ sec $\theta$ = - $\frac { 17 } { 8 }$ cot $\theta$ = - $\frac { 15 } { 8 }$
