Can someone please help me with this!!

Step-by-step explanation:

(-5, - 12) lies on the terminal side of angle \theta

\therefore \: ( - 5 \:  - 12) = (x \: y) \\ r =  \sqrt{ {x}^{2}  +  {y}^{2} } \\  =  \sqrt{ {( - 5)}^{2}  +  {( - 12)}^{2} } \\  =  \sqrt{25 + 144}  \\  =  \sqrt{169}  \\  r= 13 \\  \\  \sin \theta =  \frac{y}{r}  =  -  \frac{12}{13}  \\  \\  \cos \theta =  \frac{x}{r}  =  -  \frac{5}{13}  \\  \\  \tan \theta =  \frac{y}{x}  =   \frac{ - 12}{ - 5}  =  \frac{12}{5}  \\  \\  \csc \theta =  \frac{r}{y}  =  -  \frac{13}{12}  \\  \\  \sec \theta =  \frac{r}{x}  =  -  \frac{13}{5}  \\  \\  \cot \theta =  \frac{x}{y}  =   \frac{ - 5}{ - 12}  =  \frac{5}{12}
