Answer

$\sin\theta=\frac{y}{r}=\frac{-24}{25}$ $\cos\theta=\frac{x}{r}=\frac{7}{25}$ $\tan\theta=\frac{y}{x}=\frac{-24}{7}$ $\csc\theta=\frac{r}{y}=\frac{25}{-24}$ $\sec\theta=\frac{r}{x}=\frac{25}{7}$ $\cot\theta=\frac{x}{y}=\frac{7}{-24}$

Work Step by Step

$x=7$ $y=-24$ $r=\sqrt{(-24)^{2}+(7)^{2}}=\sqrt {576+49}= 25$
