Answer:
71.6°
Explanation:
We need to use a expression that allow us calculate the angle subtended by an arc of circle at the center of this circle.
The theory say that,[tex]\theta=\frac{L}{r}[/tex]
Where L is the distance between the two points and r the ratio from the circunference.
[tex]\theta = \frac{5000}{4000}[/tex]
[tex]\theta = 1.25rad[/tex]
We can also convert this number to degree.
[tex]\theta = 1.25*(\frac{360}{2\pi})[/tex]
[tex]\theta = 71.6\°[/tex]
