Answer:

32, consecutive interior angles are supplementary.

Step-by-step explanation:

We know that the two angles add up to 180, because consecutive interior angles are supplementary. So let's set up an equation equal to 180.

2x + 3x + 20 = 180

Now let's add like terms.

5x + 20 = 180

Now let's subtract 20 from both sides.

5x = 160

Now let's divide both sides by 5.

x = 32

WILL GIVE BRAINLIEST!!!!!!!!!!!!! the answer for question one was x=30

Fofino [41]

Answer:1

1. $x = 30$

2. ∠ABC = 120°, ∠BCD = 90°, ∠CDA = 60°, ∠DAB = 90°

Step-by-step explanation:

It's important to note here that the measure of all interior angles in a quadrilateral will add up to 360°

We know this using the formula $(n-2)\cdot 180$ , a 4 sided figures angles will add up to

$(4-2)\cdot 180\\\\2\cdot 180\\\\360$

This means that all of the angles (4x, 3x, 2x, 3x) will add up to 360.

$4x + 3x + 2x + 3x = 360$

Combine like terms:

$12x = 360$

Divide both sides by 12:

$x = 30$

We know now substitute x for 30 in for all of the side lengths.

∠ABC = 4x = $4\cdot 30 = 120$ °

∠BCD = 3x = $3\cdot 30 = 90$ °

∠CDA = 2x = $2\cdot 30 = 60$ °

∠DAB = 3x = $3\cdot 30 = 90$ °

Hope this helped!

Consider line segment AB whose endpoints are (1, 4) and (4, 8). If this segment is dilated by a scale factor of 4 centered at th

gulaghasi [49]

Answer:

The length of the new segments A'B' is 20 units ⇒ answer C

Step-by-step explanation:

* Lets revise the dilation

- A dilation is a transformation that changes the size of a figure.

- It can become larger or smaller, but the shape of the figure does

not change.

- The scale factor, measures how much larger or smaller the image

will be

- If the scale factor greater than 1, then the image will be larger

- If the scale factor between 0 and 1, then the image will be smaller

* Lets solve the problem

- line segment AB whose endpoints are (1, 4) and (4, 8) is dilated by

a scale factor of 4 and centered at the origin

∵ The scale factor is 4 and it is greater than 1

- The length of the image of line segment AB will enlarged by the

scale factor 4

∴ A'B' = 4 AB

* Lets find the length of AB by using the rule of the distance

∵ $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

∵ A = $(x_{1},y_{1})$ and B = $(x_{2},y_{2})$

∵ A = (1 , 4) and B = (4 , 8)

∴ $(x_{1},y_{1})=(1 , 4)$ and $(x_{2},y_{2})=(4 , 8)$

∵ AB = $\sqrt{(4-1)^{2}+(8-4)^{2}}=5$

∴ AB = 5 units

∵ A'B' = 4 AB

∴ A'B' = 4 × 5 = 20

∴ The length of the new segments A'B' is 20 units

Please help , I have no idea of how to do this

Misha Larkins [42]

Hello!

The time difference between checkpoint 1 and checkpoint 2 is an hour and a half.
At checkpoint A, the total amount of miles driven is 120. At checkpoint B, the total amount of miles driven is 195.
To find the amount of miles driven between checkpoint 1 and 2, you will subtract the amount of miles at checkpoint 1 from checkpoint 2:
195-120= 75

The car drove 75 miles between 1:00pm to 2:30 pm. Because the total time between the checkpoints was an hour and a half, we can divide it by three (90 minutes total). We also need to divide the number of miles (75) by three to find an accurate answer.
90/3=30
75/3=25

The car drove 25 minutes in half an hour. Now, one hour consists of 60 minutes, so we will multiply both calculations by 2 (for the total hour and the total amount of miles driven in the hour):
30x2=60
25x2=50

The car drove 50 miles per hour between checkpoints A and B.

I hope this helps you! Have a great day!
