225 degrees

Step-by-step explanation:

Given the following data;

To find the angle in degrees subtended by an arc;

Mathematically, the length of the arc of a circle is given by the formula;

S = rA

Where;

Substituting the values into the formula, we have;

22 = 5.6 * A

A = 3.9286 radians.

Next, we would convert the value of the angle in radians to degrees;

Conversion:

Cross-multiplying, we have;

X = 225.0015 ≈ 225 degrees

answer: a
