The side of the square is 6.2 cm

A square is a quadrilateral with four equal sides.

Characteristics of a square includes:

• The diagonals bisect each other at 90°.

• Opposite sides parallel and of equal length

• The four angles of a square are equal.

Area of a square = length of a side²

37.8225cm² = length of a side²

To determine the length of a side, find the square root of 37.8225cm²

√ 37.8225cm² = 6.15cm

To round off to one decimal place, look at the second number after the decimal (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

The hundredth number is 5, so one would be added to one. the number then becomes 6.2cm

Answer:

70 ft^2

Step-by-step explanation:

Find the area of the wall

A = l*w where l is the length and w is the width

A = 8 2/5 * 16 2/3

Change to improper fractions

A = 42/5 *50/3

  Rewriting

A = 42/3 * 50/5

    = 14 * 10

A = 140 ft^2

He paints 1/2

Step-by-step explanation:

The sum of the angles of a triangle is 180

Angle 1:Angle2: angle3: total

2          :2            :5          : 2+2+5 = 9

Divide 180 by 9

180/9 = 20

Step-by-step explanation:

Answer:

x = 18

Step-by-step explanation:

First, let's find the ratios between the two triangles

We'll use AV and AC

372 ÷ 589 = 12/19

All of the sides of the smaller triangle are 12/19 of the bigger triangle

Now let's find x

We know that AU + UB = AB

So it's 20x + 108 + 273 = AB

12/19 of a bigger triangle side equals a small triangle side

(12/19)AB = AU

For this equation multiply both sides by 19/12 to isolate AB

(12/19)AB x 19/12 = AU x 19/12

AB = (19/12)AU

Now we have this

20x + 108 + 273 = (19/12)(20x + 108)

20x + 381 = (19/12)(20x + 108)

Distribute the 19/12

20x + 381 = 95/3x + 171

Move all like terms to one side

20x + 381 = 95/3x + 171

       - 171                 - 171

20x + 210 = 95/3x

- 20x           - 20x

Don't forget about common denominators

210 = 95/3x - 60/3x

210 = 35/3x

Multiply both sides by 3

210 x 3 = 35/3x x 3

630 = 35x

Divide both sides by 35

630/35 = 35x/35

x = 18

Answer:

Step-by-step explanation:

[tex]\frac{20x+108}{20x+381}[/tex] = [tex]\frac{372}{589}[/tex]

589( 20x + 108 ) = 372( 20x + 381 )

11780x + 63612 = 7440x + 141732

4340x = 78120

x = 18

Answer:

7 is the answer..........

Answer:

x = 7 (C)

Step-by-step explanation:

So first we need to be able to know the value of 14x + 18. Which is 116 degrees. This is because it is corresponding to the angle labelled 116 degrees and corresponding angles are equal so:

14x + 18 = 116

14x + 18 - 18 = 116 - 18 Here you collect like terms then the equation will look like this:

14x = 116 - 18 116 - 18 = 98

14x = 98 Divide both sides by 14

14x / 14 = 98 / 14

x = 7 So your answer is 7.

HOPE THIS HELPED

Answer:

as both triangles are congruent......

AB = PQ

BC = QR

CA = RP

So AB = PA so... 2x + 1 = x + 7

so x = 7 - 1 = 6

now BC = QR so.... 4y + 3 = 2y + 11

so 2y= 8 and y= 4

Answer:

TW correspondant to AD

Step-by-step explanation:

That's the right answer

Segments TW and AD are corresponding parts of the congruent triangles.

Two triangles are called congruent if their corresponding sides and angles are congruent.

Given that,  Δ MTW ≅ Δ CAD

The congruent parts are;

MT = CA

TW = AD

MW = CD

∠ M = ∠ C

∠ T = ∠ A

∠ W = ∠ D

Hence, Segments TW and AD are corresponding parts of the congruent triangles.

Answer:

First, just  to recap, the angle that has a measure of 60 and the angle that has a measure of 2x+14 are vertical angles.

This means, that they are equal to each other.

Knowing this, the rest is pretty easy. We just set up an equation:

60 = 2x+14

And solve for x: (I'm going to speed through, but let me know if you need me to go step by step...)

2x = 46

x = 23

Answer:

Step-by-step explanation:

Using x and y to represent the 2 numbers with x > y , then

x + y = 15 → (1)

x - y = 11 → (2)

Adding the 2 equations term by term to eliminate y

2x = 26 ( divide both sides by 2 )

x = 13

Substitute x = 13 into (1)

13 + y = 15 ( subtract 13 from both sides )

y = 2

The 2 numbers are 13 and 2

The bottom left segment is rotated 1/8 turn CW from one figure to the next.

The top middle segment is rotated 1/4 turn CW from one figure to the next.

After steps, the top middle segment will be back in the same place. The lower left segment will be in the opposite corner. This corresponds to figure C.
