Answer:
The second picture. Top right.
The answer would be -48-24x
Answer:
∠ B = 45°
Step-by-step explanation:
∠ A and ∠ Bare alternate exterior angles and are congruent , then
5x - 15 = 2x + 21 ( subtract 2x from both sides )
3x - 15 = 21 ( add 15 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12
Then
∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°
We know that to find the area of the entire circle, we are going to use the equation:

And we know that the diameter is 12. To find the radius, we divide the diameter by 2, so 12/2 = 6. So the radius is 6.
Now we can use this radius in the equation:


Since all of the angles of each section are equal, we can assume that each of the sections has an equal area. There are 5 sections, so we need to divide
by 5 to find the area of each section:

Each section has an area of
or, using 3.14 for pi,
.
Since we are told to find the area of the blue sections, we know that there are 2 sections that are blue. So we need to multiply the area of each section by 2, to find the area of two of the sections:

Therefore, the answer is C) 45.2

X + z = 15
w + y = 10
(3w + 3y(2x + 2z) = 3(w + y) * 2(x + z) = 3*10 + 2*15 = 60 Answer
