In a circle, the length of an arc intercepted by a central angle is 12 mm, and the radius of the circle is 8 mm. What is the measure, in radians, of the angle?

20 or 96

Step-by-step explanation:

If the radius is 8 then half of that would be for 4 so but it ask for an angle so so it 20 or 96

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
