Answer:
46 degrees
Step-by-step explanation:
Angles 3 and 7 are corresponding angles which also means that they are congruent. Since they are congruent, angle 7 is also 46 degrees.
Total area of the gray sections of the target is 678 square inches.
Given :
Three concentric circles and we have to find the total area of the gray sections.
Area of white circle having radius 1 foot.
⇒ Area of the white circle - Area of the smaller gray circle.
⇒
⇒ <em> ...1 foot = 12 inches and 0.5 foot = 6 inches</em>
⇒ 339.12 square inches
The total area of the gray sections is the area of the bigger gray circle minus the area of the white circle.
Total area of the gray sections:
⇒ <em> ....where 1.5 foot = 18 inches</em>
⇒ square inches.
≅ 678 square inches.
The total area of the gray sections of the target, to the nearest square inch is 678.
Option C is the right choice.

Terminating decimals are decimals whose values stop at a certain digit. They are not recurring in nature. Thus, the results of the rational numbers above are terminating decimals and are solved blow.
AB = 14
We can add the segments together to find the total
AB + BC = AC
This will allow us to find x
4x+2 + 3x-1 = 22
Combine like terms
7x +1 = 22
Subtract 1 from each side
7x+1-1 = 22-1
7x = 21
Divide by 7
7x/7 = 21/7
x = 3
Now we can find the length of AB
AB = 4x+2 = 4(3)+2 = 12+2 = 14
