x= 7.5

2. adjacent angles equal 180

(2m+8)+(3m-4)= 180

WXYZ has vertices W(6,2), X(3,7), Y(-1,4), and Z(4,-2)

a)Find perimeter
b)Find the perimeter of the image of WXYZ after dilation of 1/2 centered at origin and compare it to perimeter of WXYZ

Answers

Answer:

23,11333753

Step-by-step explanation:

1. Use The Coordinates To Find The Distances Of The Four Sides

2. The Formula For Perimeter Or A Quad =

AB + BC + CD + AD

Basically Add The Distances Of The Four Sides

So: WX + XY + YZ + WZ

[tex] \sqrt{34} + 5 + \sqrt{61} + 2 \sqrt{5} [/tex]

= 23,11333753

.°. 23,1

b.????

We can write the parameter as -

P = 23.13P = 11.55

What is a quadrilateral?

In geometry a quadrilateral is a four-sided polygon, having four edges and four corners.

Given is that WXYZ has vertices W(6, 2), X(3, 7), Y(-1, 4), and Z(4, -2).

The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 - dimensional plane, the distance between points (x₁, y₁) and (x₂, y₂) is given by the Pythagorean theorem -

       {d} = √{(x₂ - x₁)² + (y₂ - y₁)²}

{ a } -

WX = 5.83

XY = 5

YZ = 7.8

ZW = 4.5

So the perimeter would be -

P = WX + XY + YZ + ZW

P = 5.83 + 5 + 7.8 + 4.5

P = 23.13

{b} - After the dilation, the sides will become -

WX' = 5.83/2 = 2.9

XY' = 5/2 = 2.5

YZ' = 7.8/2 = 3.9

ZW' = 4.5/2 = 2.25

The perimeter will be -

P = WX' + XY' + YZ' + ZW'

P = 2.9 + 2.5 + 3.9 + 2.25

P = 11.55

Therefore, we can write the parameter as -

P = 23.13P = 11.55

Answer:

Circumference =

Step-by-step explanation:

The equation for finding the circumference of a circle is: C=2πr

All we need to do is plug in for r of the equation (which is the radius) and solve.

C = 2(3.14)·12

C = 6.28 · 12

C = 75.36 mill.

Luis is running a 26 mile marathon. He has completed 75/12 miles so far. How much farther does he have to run?

Answers

Answer:

18 7/12 miles

Step-by-step explanation:

Luis is running a 26 mile marathon. He has completed 7 5/12 miles so far. How much farther does he have to run?

We solve the above question using the Subtraction operation

= 26 miles - 7 5/12 miles

= 26 miles - 89/12 miles

Lowest Common Denominator = 12

= 26/1 miles - 89/12 miles

= 312 - 89/12

= 223/12

= 18.583333333 miles

= 18 7/12 miles

He has 18 7/12 miles farther to go
