Part 1:
Prove that the two triangles above are similar. Provide a proof using any method (two-column, flow-chart, or paragraph). For whichever method you choose, include the statements that lead you to the necessary conclusion, as well as corresponding reasons for each statement.
Part 2:
Find the measures of AC and AB all necessary calculations.
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 inchesWhich 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
2. ∠DCE ≅ ∠ACB [tex]{}[/tex] 2. Vertical angle theorem
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 inchesSimilarly, 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]
[tex]{\overline{AB}} = \dfrac{15}{8} \times 16 = \mathbf{30}[/tex]

Step-by-step explanation:
Quadratic expressions are polynomial expressions in which the highest power of the variable is 2.
Looking at option A, the highest power of the variable in the polynomial is 4. Therefore, it is not a quadratic expression.
Looking at option B, the highest power of the variable in the polynomial is 3. Therefore, it is not a quadratic expression.
Looking at option C, the highest power of the variable in the polynomial is 2. Therefore, it is a quadratic expression.
Looking at option D, the highest power of the variable in the polynomial is 1. Therefore, it is not a quadratic expression.

find yz 11x+1 and 19x-31
The length of a segment is the number of units between its endpoints
The length of YZ is 45 units
How to determine length YZThe 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

Anita can iron a dress shirt in 15 minutes, but
it takes Michelle 18 minutes to do the same.
Working together, how many minutes will it take
them to iron 11 dress shirts?
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 / 15Michelle iron the same shirt for 18 minutes. Therefore,
rate = 1 / 18Let the time they use to work together = x
Therefore,
1 / x = 1 / 15 + 1 / 181 / x = 18 + 15 / 270
1 / x = 33 / 270
cross multiply
270 = 33x
x = 270 / 33
x = 90 / 11
Both of them will use 90 / 11 minutes to iron a dress shirt
Therefore, 11 dress shirt will be ?
number of minutes to iron 11 dress shirt together = 11 × 90 / 11 = 90 minutes

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