Answer:

Step-by-step explanation:

$\cot( \alpha ) = \frac{1}{ \tan( \alpha ) }$

$\alpha_{lll} = \frac{5\pi}{4} - \pi \\ \\ \alpha_{lll} = \frac{\pi}{4}$

$\cot( \frac{\pi}{4} ) = \frac{1}{ \tan( \frac{\pi}{4} ) } \\ \cot( \frac{\pi}{4} ) = \frac{1}{ 1} = 1$

The radius of a circle is 12 miles. What is the angle measure of an arc bounding a sector with area 10 square miles?

$\bf \textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad degrees\\[-0.5em] \hrulefill\\ A=10\\ r=12 \end{cases}\implies 10=\cfrac{\theta \pi 12^2}{360}\implies 10=\cfrac{2\pi \theta }{5} \\\\\\ 20=2\pi \theta \implies \cfrac{20}{2\pi }=\theta \implies \cfrac{10}{\pi }=\theta \implies 3.18\approx \theta$
