Answer:
Step-by-step explanation:
The formula for the length of an arc is
[tex]L=\frac{\theta}{360}*2\pi r[/tex]
We have L = 123.53 and twice the radius as 56. Filling in:
[tex]123.53=\frac{56\pi \theta}{360}[/tex]
Begin by multiplying both sides by 360 to get
[tex]44470.8=56\pi \theta[/tex] and divide both sides by 56π to get
θ = 253°
