The measure of the arc (S) given the angle it intercepted (A) and the radius is given by the equation,
                                     S = (A / 360°) x (2πr)
Substituting the values to the equation above,
                                       4 ft = (A / 360°) x (2π)(10 ft)
The value of A is 22.92°.

Answer:

22.92 degrees.

Step-by-step explanation:

We have been given that

s = 4 ft

r = 10 ft

We have to find the angle in degrees.

We know the relation

\(\theta=\frac{s}{r}\)

Here angle is in radians.

Substituting the values, we get

\(\theta=\frac{4}{10}\\\\\theta=\frac{2}{5}\text{ radians}\\\\\theta=0.4\text{ radians}\)

1 radian = 57.2958 degrees.

Hence, 0.4 radians = 22.92 degrees.

Therefore, the degree measure of the angle is 22.92 degrees.
