Answer:

C) 1/2(y-127) = 53

Step-by-step explanation:

When an angle is formed by two secants, a secant and a tangent, or two tangents, the measure of the angle is equal to one-half of the difference between the intercepted arcs.

In this circle, our intercepted arcs are y° and 127°.  Their difference would be (y-127).  One-half of this would be 1/2(y-127).  The angle measure is 53; this gives us

1/2(y-127) = 53

hope this helps c:

a circular dog pen has a circumference of 78.5 feet. approximate by 3.14 and estimate how many hunting dogs could be safely kept
olasank [31]

Answer:

  8

Step-by-step explanation:

To solve this problem, we need to find the area of the pen, then divide that by the area required by each dog.

__

The relationship between circumference and radius is ...

  C = 2πr

Solving for r gives ...

  r = C/(2π)

The relationship between radius and area of a circle is ...

  A = πr²

Substituting for r from above gives ...

  A = π(C/(2π))² = C²/(4π)

Filling in the given numbers, we find the area of the pen to be ...

  A = (78.5 ft)²/(4·3.14) = 490.625 ft²

__

Dividing the pen area by the area per dog gives the number of dogs the pen can hold:

  (490.625 ft²)/(60 ft²/dog) ≈ 8.18 dogs

The pen can safely keep 8 dogs.

- How is the formula for the perimeter of a rectangle an application of the Distributive Property
N76 [4]
Distributive is
a(b+c)=ab+ac
ab+ac=a(b+c)

perimiter of a rectangle=distance around

we have
P=L+W+L+W if we go around
so
P=L+L+W+W
P=2L+2W
undistribute 2
P=2(L+W)
