Answer correctly for brainliest pleaseeee!!!!

Use rotation, and the angles and side lengths remain the same.

ACB=BED

BAC=BDE

ABC=EBD

AC=ED

AB=BD

BE=CB

Rotation rigid transformation can be used to map triangle ABC on to triangle DBE.

The angles ACB, BAC, ABC of given image are equals to the angles of preimage BED, BDE and EBD respectively. That is

ACB=BED

BAC=BDE, and

ABC=EBD

Also the sides AC, AB, and BE of the given image are equals to the sides of preimage ED, BD, and CB respectively. That is

AC=ED

AB=BD, and

BE=CB

The corresponding sides are

AC and DE

AB and BD

CB and EB

And the corresponding angles are

∠ACB and ∠BED

∠ABC and ∠EBD

∠CAB and ∠EDB

A rigid transformation or an isometry is a transformation that does not change the sides and angle of plane figures.

The three types of rigid transformation are:

1) Translation

2) Reflection

3) Rotation

According to the given question.

Triangle ABC is transformed to triangle DBE.

(a) Rotation rigid transformation can be used to map triangle ABC on to triangle DBE. If we rotate triangle ABC at 180 in clockwise direction the triangle ABC maps on to triangle DBE. ( A rotation is followed by another rotation).

(b) The angles ACB, BAC, ABC of given image are equals to the angles of preimage BED, BDE and EBD respectively. That is

ACB=BED

BAC=BDE, and

ABC=EBD

Also the sides AC, AB, and BE of the given image are equals to the sides of preimage ED, BD, and CB respectively. That is

AC=ED

AB=BD, and

BE=CB

(c) The corresponding sides are

AC and DE

AB and BD

CB and EB

And the corresponding angles are

∠ACB and ∠BED

∠ABC and ∠EBD

∠CAB and ∠EDB

Answer:

x = 12

Step-by-step explanation:

9 * 25 = 225

225 - 6 = 219

There are 219 chairs left.

Answer:

219 Chairs are left.

Step-by-step explanation:

[tex]\rightarrow[/tex] Each row has 25 chairs. And there are total 9 rows.

So, total number of chairs = 25×9

= 225

➾ Workers removed 6 chairs, so left number of chairs = 225-6

= 219 chairs.

ANSWER: C. Angle s

Answer:

Tbh I am not sure but it's a semi-circle prism or like semi cylinder (I think) but usually semi-circles themselves will not tessellate bc circles have no angles and when u line them up next to each other there will be gaps between them and one of the tessellation rules is that no overlapping or gaps so yeah

I am sorry lol if that's all wrong but my answer is no, I don't think that this figure is a tessellate plane

Answer:

Step-by-step explanation:

Here is the equation for this problem:

2 1/2 + 1 3/4 + x = 12

To add 2 1/2 and 1 3/4, revert the fractions into mixed numbers, and then change the denominator to the LCM (Lowest Common Denominator)

3/2 + 7/4 + x = 12

The lowest common denominator, in this case, is 4. 7/4 stays the same because the denominator is already 4, but we need to multiply the numerator and denominator of 3/2 by two to get the denominator to 4. (Whatever you do to the numerator, you have to do to the denominator, and vice versa)

3 x 2 = 6

2 x 2 = 4

Now, the equation looks like this:

6/4 + 7/4 + x = 12

Now add the fractions. The denominator stays the same, but the numerators are added together.

6/4 + 7/4 = 13/4

Now, you can revert 13/4 back to a mixed number

13/4 = 3 1/4

The equation should look like this now:

3 1/4 + x = 12

Now subtract 3 1/4 from both sides (Meaning subtract 3 1/4 from 3 1/4 to cancel it out and also subtract 3 1/4 from 12 as well)

12 - 3 1/4 = 8 3/4

Now, it should look like this:

x = 8 3/4

You could change the 8 3/4 into a decimal as well, which would look like this:

x = 8.75

Here is a summary of the whole equation:

2 1/2 +  1 3/4 + x = 12

3/2 + 7/4 + x = 12

6/4 + 7/4 + x = 12

13/4 + x = 12

3 1/4 (-3 1/4) + x = 12 (-3 1/4)

x = 8 3/4 or 8.75 acres

Answer:

Lisa has 8 3/4 acres left for home sites

There will be 7.75 acres of land left for home sites.

Mixed fractions are type of fractions which includes both a whole part and a fractional part.

It is of the form a [tex]\frac{b}{c}[/tex], where a is the whole part and b/c is the fractional part. This actually implies that a +  [tex]\frac{b}{c}[/tex]. So we can do the cross multiplication to change the mixed fraction into improper fraction.

Total land for housing development = 12 acres

Land covered by park = 2 [tex]\frac{1}{2}[/tex]

                                     = (2 × 2 + 1) / 2

                                     = 5/2 acres

Land covered by paved areas = 1 [tex]\frac{3}{4}[/tex]

                                                  = (1 × 4 + 3) / 4

                                                  = 7/4 acres

Total land covered by park and paved areas = [tex]\frac{5}{2}[/tex] + [tex]\frac{7}{4}[/tex]

                                                                           = [tex]\frac{10}{4}[/tex] + [tex]\frac{7}{4}[/tex]

                                                                           = [tex]\frac{17}{4}[/tex]

                                                                           = 4.25 acres

So the remaining land = 12 - ([tex]\frac{5}{2}[/tex] + [tex]\frac{7}{4}[/tex])

                                     = 12 - 4.25

                                     = 7.75 acres

Hence Lisa can build the home sites in the remaining 7.75 acres of land.

Answer:

7.) 53.38

8.) 18.84

9.) 87.92

Step-by-step explanation:

7.)

For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.

The formula for finding the circumference is 2 × π × 8.5

2 × 3.14(π) = 6.28.

6.28 × 8.5 = 53.38

8.)

For the second question, we can see that the radius is now given to us which is 3ft.

The formula for finding the circumference is 2 × π × 3

2 × 3.14(π) = 6.28.

6.28 × 3 = 18.84

9.)

For the third question the raduis is also given to us, which is 14 in.

The formula for finding the circumference is 2 × π × 14.

2 × 3.14(π) = 6.28.

6.28 × 14 = 87.92
