Answer :
The correct answer is 45.28°
In order to get that answer, you must set up the arc length formula.
l = m/360 • 2πr
4.9 = m/360 • 12.4π
We are trying to find the angle measure; therefore, we are going to divide.
4.9 = 0.10821m
Flip the equation
0.10821m = 4.9
0.10821m/0.10821 = 4.9/0.10821
m = 45.28°

We can use the formula angle = (arc length / radius) or an online calculator to find the angle of the slice, which is approximately 47 degrees in this case.
To find the measure of the angle of one slice of pizza, we can use the formula:
angle = (arc length / radius)
However, we are not given the radius of the pizza, so we first need to find it. One way to do this is to use the length of one side of the slice and the central angle of the slice. We know that the central angle of the slice is twice the angle at the center of the pizza that the slice occupies, so we can find this angle by:
angle at center = (angle of slice) / 2
We can then use the law of cosines to find the length of the radius:
radius² = (side length / 2)^2 + (side length / 2)² - 2 * (side length / 2) * (side length / 2) * cos(angle at center)
Once we have the radius, we can use the formula above to find the angle of the slice. However, since this calculation can be quite involved, it may be simpler to use an online pizza slice angle calculator. Using this tool with the given values, we find that the angle of one slice of pizza is approximately 47 degrees.
