Answer:
<h2>
E) 84</h2><h2 />
Step-by-step explanation:
side AB is congruent to side AX
this means that the angle ∠A = 4x is the same angle as ∠Z
therefore ∠A = ∠Z = 4x
inside angle of a triangle = 180
∠A + ∠B + ∠Z = 180
4x + 7x + 4x = 180
15x = 180
x = 180/15
x = 12
now substitute x = 12 into angle B
∠B = 7x
∠B = 7 (12)
∠B = 84
therefore, the answer is E) 84
3(4x - 2) = 2(6x - 3)
First, expand. / Your problem should look like: 12x - 6 = 12x - 6
Second, since both sides are equal, there and infinite solutions.
Answer: B) infinite solutions.
600%? Would it be if one is 100%?
Answer: The answer is 
Step-by-step explanation: Given that the area of the whole circle is represented by the expression

We are to find the area of the outer ring of the circle, i.e., to find the circumference of the circle.
Now, if 'r' represents the radius of the circle, then we have

Thus, the area of the outer ring is
