A two column proof for ΔAEC ≅ ΔDEB  is as shown below.

What are congruent triangles?

"Two triangles are congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure."

What are interior angles?

"These angles formed on the inside of two straight lines when crossed by a transversal."

What is midpoint?

"It is point which divides a line segment into two equal parts."

What is AAS postulate of triangle congruence?

"AAS (Angle Angle Side) theorem states that in the two triangles, if two angles and one side of a triangle are congruent to two angles and one side of a second triangle, then the two triangles are congruent."

For given question,

Given that CA is parallel to DB and E is the midpoint of AD.

CA is parallel to DB

CB is transversal.

∠ACB and ∠CBD are alternate interior angles.

We know that when a transversal intersects a parallel line then alternate interior angles formed are congruent.

So, ∠ACB ≅ ∠CBD                       ................(i)

Similarly for CA || DB and AD is transversal.

∠CAD ≅ ∠ADB                             ..................(ii)

Also,  E is the midpoint of AD.

By definition of midpoint,

⇒ AE = ED                                      ..................(iii)

From (i), (ii) and (iii),

By AAS postulate of triangle congruence,

ΔAEC ≅ ΔDEB      

Therefore, a two column proof for ΔAEC ≅ ΔDEB  is as shown below.

Solve 4\left| {x + 5} \right| + 8 = 244∣x+5∣+8=24.

Answers

Isolate the absolute value term:

4 |x + 5| + 8 = 24

4 |x + 5| = 16

|x + 5| = 4

By definition of absolute value,

• if x + 5 ≥ 0, then |x + 5| = x + 5, and so

x + 5 = 4

x = -1

• otherwise, if x + 5 < 0, then |x + 5| = -(x + 5), and so

-x - 5 = 4

-x = 9

x = -9

A bedroom door has a perimeter of 26 feet and an area of 36 square feet. What are the dimensions of the door?

Answers

4 and 9

Because 4+4+9+9=26

And 4x9=36

You can use trial and error or substitution.

Equation 1. 2x + 2y = 26
Equation 1. x = 13 - y

Equation 2. xy = 36
Equation 2. x = 36/y

Equation 1 = Equation 2 to equal equation 3. Then move all the terms to one side and factorise to get your answer.

Equation 3. 13 - y = 36/y
Equation 3. y squared - 13y + 36 = 0
Equation 3. (y - 4)(y - 9)
y = 4 or 9

Therefore the dimensions are 4 and 9

please help me find DE

Answers

You can split up the length of AE into the lengths of the line segments connecting adjacent points:

AE = AB + BC + CD + DE

Plug in everything you know and solve for DE :

9 = (2 1/2) + (4 1/3) + (1 2/3) + DE

Rewrite the mixed numbers as improper fractions with a common denominator.

2 1/2 = 4/2 + 1/2 = 5/2 = 15/6

4 1/3 = 12/3 + 1/3 = 13/3 = 26/6

1 2/3 = 3/3 + 2/3 = 5/3 = 10/6

9 = 54/6

So we have

54/6 = 15/6 + 26/6 + 10/6 + DE

⇒   DE = (54 - 15 - 26 - 10)/6 = 3/6 = 1/2

In centimeters, what is the unknown length in this right triangle?
A right triangle with side length 60 centimeters, x, and hypotenuse of 61 centimeters.

Answers

Answer:

Given:-

Side length ( perpendicular = 60 cm)

Hypotenuse = 61 cm

To find :-

Base length

Solution:

By Pythagoras theorem ,

Hypotenuse² = Perpendicular² + Base²

61² = 60² + base²

3721-3600 = Base²

√121 = base

11cm = base

Answer:

Base = x = 11 cm

Step-by-step explanation:

In the question we are given ,

Side length ( Perpendicular ) = 60 cm

Hypotenuse = 61 cm

And we have asked to find the length of base that is denoted by x .

Solution : -

According to Pythagoras Theorem ,

[tex] \longrightarrow \purple{\boxed{H {}^{2} = P {}^{2} + B {}^{2} }} \longleftarrow[/tex]

Where ,

H = Hypotenuse

P = Perpendicular

B = Base

Now , substituting value of hypotenuse, perpendicular and base :

[tex] \hookrightarrow \: 61 {}^{2} = 60 {}^{2} + x {}^{2} [/tex]

Now by squaring 61 and 60 , we get :

[tex] \hookrightarrow \:3721 = 3600 + x {}^{2} [/tex]

Now transposing 3600 to left hand side :

[tex] \hookrightarrow \:3721 - 3600 = x {}^{2} [/tex]

Now subtracting 3600 from 3721 :

[tex] \hookrightarrow \:121 = x {}^{2} [/tex]

[tex] \hookrightarrow \: \sqrt{121} = x[/tex]

We know that 11 × 11 is equal to 121 that means square root of 121 is 11 . So :

[tex] \hookrightarrow \: \red{ \boxed{11 \: cm = x}}[/tex]

x = base

Henceforth, length of base of right triangle is 11 cm .

But for AG im kind of stuck. At first I thought it was 11 but then just by looking at it you can see that they aren't the same length(I mean AG and GC) so I don't know about that one.

heres what I THINK it could be

GF and GD COULD BE the same length, considering that this is a 3d shape.

So, since AGF is a right triangle, we can use pythagorem. theorem.

7^2+9^2=x^2

49+81=x^2

130=x^2

x==11.40

Answers

The length XY of the circle X is the radius of the circle

The length of XY is 9 units

How to determine the length of XY?

The parameters are given as:

Length of arc, YZ = 5πCentral angle, YXZ = 100°

The length of arc is calculated using:

L = Ф/360 * 2πr

Where:

L = YZ = 5πФ = YXZ = 100°Radius, r = XY

So, we have:

5π = 100/360 * 2πr

Evaluate the quotient

5π = 5/9 * πr

Divide both sides by 5π

1 = 1/9 * r

Multiply both sides by 9

r = 9

This means that

XY = r = 9

Hence, the length of XY is 9 units
