What is the degree measure of an arc 4 ft. long in a circle of radius 10 ft.?

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

Here angle is in radians.

Substituting the values, we get

1 radian = 57.2958 degrees.

Hence, 0.4 radians = 22.92 degrees.

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

a negative exponent is translated as follows:

so, we have

1. perpendicular

2. parallel

3. perpendicular
