Answer 1

Given

The point,

`(-8,-√(17))`

To find the value of csc theta.

Step-by-step explanation:

It is given that,

`The\text{ point is }(-8,-√(17))`

Then,

`\begin{gathered} \alpha=\tan^(-1)|(-√(17))/(-8)| \\ =\tan^(-1)|(√(17))/(8)| \\ =0.47588 \end{gathered}`

Therefore,

`\begin{gathered} \theta=-\tan\alpha \\ =-0.47588 \end{gathered}`

Hence,

`\begin{gathered} csc\theta=csc(-0.47588) \\ =-csc(0.47588) \\ =2.1828 \end{gathered}`
