To answer this question we will use the following formula for the angle corresponding to a complex number z:

$\theta=\arctan (\frac{\operatorname{Im}(z)}{\operatorname{Re}(z)})\text{.}$

In this case:

$\begin{gathered} \operatorname{Re}(z)=8, \\ \operatorname{Im}(z)=-9. \end{gathered}$

Therefore:

$\theta=\arctan ((-9)/(8))\approx-0.844.$

Answer:

$\theta=-0.844.$
