AB is congruent to DE because segment DE was constructed so that DE = AB. BC is congruent to EF because segment EF was constructed so that EF = BC. Since ADEF is a right triangle, DE+ EF? = DF? by the We are given that AB + BC2 = AC? Since DE = AB and EF = BC, DE2 + EF2 = AC? by the Also, DF2 = AC2 by the Taking the square root of both sides of the equation gives DF = AC. So, AC is congruent to DF by the definition of congruence. Applying the AABC - ADEF. By CPCTC, ZB _ZE. Therefore ZB is a right angle and AABC is a right triangle.

Answers

DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.

Congruent shape

Two shapes are said to be congruent if they have the same shape, all their corresponding angles and sides are congruent to one another.

Given that DE = AB and BC = EF.

In right triangle DEF, using Pythagoras:

DF² = DE² + EF²

Also, In right triangle ABC, using Pythagoras:

AC² = AB² + BC²

But DE = AB and EF = BC, hence:

AC² = DE² + EF²

AC² = DF²

Taking square root of both sides, hence:

AC = DF

Since DE = AB, EF = BC and AC = DF, hence triangle ABC is congruent to triangle DEF.

Expression giving the result of the perimeter of rectangle A and demonstrating  the closure property is given by: Option A: [tex]10x + 4[/tex] ; the answer is a polynomial

What is the closure property of a polynomial for addition operation?

Closure property keeps the result in the same set.

If two polynomials [tex]f(x)[/tex] and [tex]g(x)[/tex] are there.

Then, [tex]f(x) + g(x) = h(x)[/tex]

where [tex]h(x)[/tex] is also a polynomial.

The result of the addition of two polynomials is also a polynomial. This property of polynomial for addition operation is called closure property of a polynomial for addition operation

For the given case, we have:

Length of the rectangle = [tex]3x + 5[/tex]Width of the rectangle = [tex]2x -3[/tex]

Perimeter of a rectangle with width W and length L = 2(L + W)

And using that formula, the perimeter of the considered rectangle is evaluated as:

[tex]P = 2(3x + 5 + 2x - 3)\\P = 2((3+2)x + 2) = 2(5x + 2)\\\\P = 10x + 4[/tex]

Thus, expression giving the result of the perimeter of rectangle A and demonstrating  the closure property is given by: Option A: [tex]10x + 4[/tex] ; the answer is a polynomial

The condition of two congruent angles in each triangle, can be used to

show that the two triangles are similar.

Response:

Part 1: The two triangles are similar by AA similarity postulatePart 2: AC = 22.5 inches, AB = 30 inches

Which condition of similarity makes the two triangles similar?

Part 1:

A two column proof is presented as follows;

Statement [tex]{}[/tex]                                    Reason

1. ∠D ≅ ∠A [tex]{}[/tex]                                   1. Given

3. ΔCDE ~ ΔCAB [tex]{}[/tex]                         3. AA similarity postulate

Angle-Angle, AA, similarity postulate states that if two angles in one

triangle are congruent to two angles in a second triangles, then the two

triangles are similar.

Part 2:

From part 1, we have;

ΔCDE is similar to ΔCAB (ΔCDE ~ ΔCAB)

The ratio of corresponding sides of similar triangles are equal, which

gives;

[tex]\dfrac{\overline{CD}}{\overline{AC}} = \mathbf{\dfrac{\overline{CE}}{\overline{CB}}}[/tex]

Which gives;

[tex]\dfrac{12}{\overline{AC}} = \mathbf{\dfrac{8}{15}}[/tex]

[tex]\overline{AC}} = \dfrac{15}{8} \times 12 = \mathbf{22.5}[/tex]

AC = 22.5 inches

Similarly, we have;

[tex]\dfrac{\overline{DE}}{\overline{AB}} = \mathbf{\dfrac{\overline{CE}}{\overline{CB}}}[/tex]

Which gives;

[tex]\dfrac{16}{\overline{AB}} = \dfrac{8}{15}[/tex]

find yz 11x+1 and 19x-31

Answers

The length of a segment is the number of units between its endpoints

The length of YZ is 45 units

How to determine length YZ

The given parameters are:

WX = 11x + 1

YZ = 19x - 31

Lengths WX and YZ are congruent.

So, we have:

[tex]19x - 31 = 11x +1[/tex]

Collect like terms

[tex]19x - 11x = 31 +1[/tex]

Evaluate the like terms

[tex]8x = 32[/tex]

Divide both sides by 32

[tex]x = 4[/tex]

Recall that:

YZ = 19x - 31

So, we have:

[tex]YZ = 19*4- 31[/tex]

[tex]YZ = 45[/tex]

Hence, the length of YZ is 45 units

Range is one of the important description of a data set. The range of the given data sets is given as:

Range of set 1 is 37Range of set 2 is 9Range of set 3 is 65Range of set 4 is 63

How to find the range of a set of data values?

Range = Maximum value of the data set - Minimum value of the data set.

For the given sets, we get their range as:

Set 1: 48, 47, 34, 37, 11, 39

Maximum value = 48, minimum value = 11

Range of the data set = Maximum value - minimum value = 48-11 = 37

Set 2: 42, 47, 44, 40, 41, 49, 48, 45, 43

Maximum value = 49, minimum value = 40

Range of the data set = Maximum value - minimum value = 49 - 40 = 9

Set 3: 85, 98, 31, 96, 49, 77, 82

Maximum value = 96, minimum value = 31

Range of the data set = Maximum value - minimum value = 96-31=65

Set 4:  112, 114, 116, 175, 115, 134, 117

Maximum value = 175, minimum value = 112

Range of the data set = Maximum value - minimum value = 175-112 = 63

Thus, the range of the given data sets is given as:

Range of set 1 is 37Range of set 2 is 9Range of set 3 is 65Range of set 4 is 63

them to iron 11 dress shirts?

Answers

The number of minutes it will take both of them to iron 11 dress shirt is 90 minutes

Rate:

Rate is the ratio between two related quantities in different units. Therefore,

Anita iron a shirt in 15 minutes. Therefore,

rate  = 1 / 15

Michelle iron the same shirt for 18 minutes. Therefore,

rate = 1 / 18

Let the time they use to work together = x

Therefore,

1  / x  = 1 / 15 + 1  / 18

1  / x =  18 + 15 / 270

1 / x = 33 / 270

cross multiply

270 = 33x

x = 270 / 33

x = 90 / 11
