Given: st=3x+3 tu=2x+9.
a. what is the value of st?
b. what is the value of tu?

We have that  the value of ST and the value of TU is

ST=21

TU=21

From the question we are told that

Where T is the mid point

Generally the equation for the T  is mathematically given as

Solving the equation

x=6

Therefore

And

TU=21

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
