TWVU is a trapezoid with midsgment FG find the value of x please help
photoshop1234 [79]

Answer:

Find each measure.

1. 

SOLUTION:  

The trapezoid ABCD is an isosceles trapezoid. So,

each pair of base angles is congruent. Therefore,

ANSWER:  

101

2. WT, if ZX = 20 and TY = 15

SOLUTION:  

The trapezoid WXYZ is an isosceles trapezoid. So, the

diagonals are congruent. Therefore, WY = ZX.

WT + TY = ZX

WT + 15 = 20

WT = 5

ANSWER:  

5

COORDINATE GEOMETRY Quadrilateral

ABCD has vertices A(–4, –1), B(–2, 3), C(3, 3),

and D(5, –1).

3. Verify that ABCD is a trapezoid.

SOLUTION:  

First graph the points on a coordinate grid and draw

the trapezoid.

Use the slope formula to find the slope of the sides of

the trapezoid.

The slopes of exactly one pair of opposite sides are

equal. So, they are parallel. Therefore, the

quadrilateral ABCD is a trapezoid.

ANSWER:  

ABCD is a trapezoid.

4. Determine whether ABCD is an isosceles trapezoid.

Explain.

SOLUTION:  

Refer to the graph of the trapezoid.

Use the slope formula to find the slope of the sides of

the quadrilateral.

The slopes of exactly one pair of opposite sides are

equal. So, they are parallel. Therefore, the

quadrilateral ABCD is a trapezoid.

Use the Distance Formula to find the lengths of the

legs of the trapezoid.

The lengths of the legs are equal. Therefore, ABCD

is an isosceles trapezoid.

ANSWER:  

isosceles;

5. GRIDDED REPSONSE In the figure, is the

midsegment of trapezoid TWRV. Determine the value

of x.

SOLUTION:  

By the Trapezoid Midsegment Theorem, the

midsegment of a trapezoid is parallel to each base

and its measure is one half the sum of the lengths of

the bases.

 are the bases and   is the 

midsegment. So,

Solve for x.

16 = 14.8 + x

1.2 = x

ANSWER:  

1.2

NEED HELP ASAP!! Our teacher never taught my class this and its on our homework. someone please help!!! i'll give brainliest to
Dennis_Churaev [7]

Answer:

  • m∠ABX = (12+4y)°
  • equation: (12+4y) +y = 92
  • m∠ABX = 76°
  • m∠CBX = 16°

Step-by-step explanation:

The reason this is titled "Mathematical Connections" is because you're supposed to draw upon all of the things you have learned about angles and equations and put them together to solve this problem. No problem-specific teaching should be necessary.

__

The words and diagram tell you that ...

  m∠ABX + m∠CBX = 92°

They also tell you that ...

  m∠CBX = y°.

The words tell you that m∠ABX = 12° + 4(m∠CBX). Since m∠CBX = y°, this means ...

  m∠ABX = (12 +4y)° . . . . . this expression fills the box on the diagram

__

So, we have expressions involving y for each of the parts of angle ABC. We can substitute those expressions into the angle sum equation to get

  (12 +4y) + (y) = 92 . . . . . . dropping the degree symbol, using only numbers

__

Using what you know about algebra and 2-step equations, you can solve this to find the value of y.

  5y +12 = 92 . . . . . simplify

  5y = 80 . . . . . . . . subtract 12

  y = 16 . . . . . . . . . . divide by 5

This value can be substituted back into the expressions for angle measure:

  m∠CBX = y° = 16°

  m∠ABX = (12+4y)° = (12 +4·16)° = 76°
