Answer:

<h2>A. Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.</h2>

Step-by-step explanation:

The first choice describes the right way to find the length of an arc in a circle.

The length of an arc is defined as

$L=2\pi r (\frac{\theta}{360\°} )$

Where $2\pi r$ represents the circumference of the circle and $\theta$ represents the arc's degree measure.

So, as you can observe through this formula, we need to divide the arc's degree measure by 360°, and then multiply this result with the circumference of the circle, that's the right way based on the definition of arc length.

Therefore, the right answer is A.

Alenkinab [10]

We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.
