R, S and T are collinear. RS = 2x + 10
ST = x - 4
RT = 21
Solve for RS
Group of answer choices
A. RS = 5
B. RS = 10
C. RS = 19
D. RS = 20

the answer would be c:   ax + b = ax + c

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
