How do you do this Please help

sergejj [24]

Answer:

The answer is 68°.

Step-by-step explanation:

Following the arc length equation:

s = r * θ where s is arc length, r is radius of the circle, and θ is the angle in radians.

12 is the Radius of the Circle and therefore solve for θ:

θ = $\frac{s}{r}$ = $\frac{\frac{68\pi }{15} }{12}$ = $\frac{17\pi }{45}$ rad. or radians

Now, convert the radians to degrees:

$\frac{17\pi }{45}$ = 68°
