Answer:

  • 102 + (3x +2) = 180 . . . . equation to solve
  • x = 25 1/3 . . . . . . . . . . . . value of x

Step-by-step explanation:

It can be helpful to draw a diagram of a parallelogram ABCD and identify the angles in the problem statement. You will find they are adjacent angles.

Adjacent angles in a parallelogram are supplementary, so the sum of the given angle measures will be 180°.

  102 + (3x +2) = 180 . . . equation used to solve for x

  3x = 76 . . . . . . . . . . . . . subtract 104

  x = 76/3 . . . . . . . . . . . . divide by 3

  x = 25 1/3 . . . the value of x

Use the information given in the diagram. Tell why UW=UW and UVW=WXU.
kow [346]

Answer:

The correct option is D.

Step-by-step explanation:

Given the figure in which UV=XW, UX=VW and ∠UXW=∠UVW.

We have to tell why UW=UW and ∠UVW=∠WXU.

As the reflexive property of equality states that a value is equal to itself.

Hence, in quadrilateral UVWX,

UW is equal to UW by reflexive property

∠UVW=∠WXU as given

hence, UW=UW and ∠UVW=∠WXU by reflexive property and given in diagram.

The correct option is d)

I'm assuming you want the total surface area.

This is a trapezoidal prism. The bases are the parallel faces running horizontal (parallel to the ground) and they are congruent trapezoids. The lateral sides are rectangles.

-------------------------------------------------

Lateral Faces:
The back face (hidden from view) is a rectangle that is 12 inches by 3 inches, so it has an area of 12*3 = 36 sq inches

The front slant faces on the left and right are each 3*5 = 15 sq inches in area

The front center lateral face has area of 6*3 = 18 sq inches

The total lateral surface area is 15+18+15+36 = 84 sq inches

-------------------------------------------------

The bases are each the same trapezoid. The trapezoid has two parallel sides of 12 and 6 inches. Call this b1 and b2. The height of the trapezoid is h = 4. Imagine the trapezoid is laid flat in a 2D perspective instead of a 3D one.

The area of one trapezoid is...
A = h*(b1+b2)/2
A = 4*(12+6)/2
A = 4*(18)/2
A = 72/2
A = 36

So the area of both base faces combined is 2*36 = 72

-------------------------------------------------

The total surface area is then found by adding the total lateral surface area (84) and the total base area (72) to get 84+72 = 156

Final Answer: 156 square inches

The use of ratio language was used in the following sentences:

For every 1 students out of school, there are 10 students in school

For every 5 apples John eats, he eats 20 boxes of chocolate

For every 5 minutes,  study, I sleep for 1 hour

Ratio is used to show the relationship that exists between numbers. It shows the frequency of the number of times that value of one number is contained within the value of another number or numbers

For example, There are 3 apples and 20 oranges. If I want to express the relationship between apples and oranges as a ratio. The ratio will be 3 : 20 . It means for every 3 apples, there are 20 oranges.
