ΔDEF

Step-by-step explanation:

Pay attention to order of vertices when comparing the congruent parts or figures.

ΔCBA ≅ ΔDEF

C and D as well as B and E are corresponding vertices according to angle marks and side marks.

In ∆ABC and ∆DEF

AB=EFBC=EDAC=FD

find the slope of the line that passes through the points (-2 3 )and( 4 3)​

Answers

Step-by-step explanation:

Given points,

( -2 , 3) and (4,3)

we know,

slope = y_2 - y_1 / x_2 - x_1

so according to it we got,

→ (3 - 3)/4 - (-2)

→ 0/6

hope this answer helps you dear! take care.

Hello!

To find the slope when we have 2 points, we use the following formula:

m=[tex]\frac{y2-y1}{x2-x1}[/tex]

m=[tex]\frac{3-3}{4-(-2)} \\\frac{0}{6} \\0[/tex]

Here's something for you to remember:

When the y-coordinates of two points are the same, the slope is 0.

Hope it helps!

x3 x3

Answer:

8

7

Step-by-step explanation:

24 purple

green : purple = 1 : 3

g / p = 1/3

g / 24 = 1/3

g = 24/3

g = 8

now abbi put x green crayons into box

now green : purple = 5 : 8

(8 + x) / 24 = 5/8

8 + x = 5/8 * 24

8 + x = 5 * 3

8 + x = 15

x = 15 - 8

x = 7

Find the values of x and y.

Answers

Answer:

x= 38

y= 71

Step-by-step explanation:

The triangle shown in the figure is an isosceles triangle, a triangle having two sides equal.

The two sides marked with a "dash" are said to be equal.

STEP I:

If we label off the triangle as ABC with AD being the extended length (containing 108°).

We'll get,

AB = AC

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

STEP II:

*Property*

"If two sides of a triangle are equal their corresponding base angles are equal too."

=> ∠BAC = ∠BCA . . . . (¡)

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

STEP III:

From the figure, ∠BCA is equal to y.

*Property*

"Two angles on a straight line sum up to 180°"

∠BAC can be found out by subtracting 109° from the straight angle (180°).

=> ∠BAC = 180 - 109

=> ∠BAC = 71°

Substituting these values in eqn. (¡):

71 = y

Hence, the value of y is 71°

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

STEP IV:

*Property*

"The exterior angle(angle on the extended side) of a triangle is equal to the sum of it's interior opposite angles."

Here,

Interior angles = x and y (= 71)Exterior Angle = 109°

=> 109 = x + 71

=> 109 - 71 = x

=> x = 38°

Hence, the value of x is 38°.

Step-by-step explanation:

A triangle has 180 degrees.

You need to add up all the ratios 1+3+6

Then divide that by 180----> 180/10=18

Answer:

Step-by-step explanation:

You are working with 1 large square made up of 100 little squares. The little squares make up 10 columns of 10 little squares each.

A

Shaded part = 30 squares.

Entire large square = 100 small squares

% = 30 / 100 * 100 = 30%

B

Shaded part = 20 horizontal squares.

Entire large square = 100 small squares

% = 20 / 100 * 100 = 20%

C

Shaded part = 5 by 5 little squares = 25 little squares

Entire large square = 100 small squares

% = 25 / 100 * 100 = 25%

Answers

Answer:

8

Step-by-step explanation:

100 = x^2 + AC^2

17^2 = AC^2 + (21 - x)^2

289 = AC^2 + 21^2 + x^2 - 2*21*x

289 = AC^2 + 441 + x^2 - 42x

from 1st equation AC^2 + x^2 = 100

289 = 441 + 100 - 42x

289 = 541 - 42x

42x = 541 - 289 = 252

x = 252/42 = 6

so AC^2 = 100 - 6^2 = 100 - 36 = 64

AC = 8

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.

x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36

Answers

Answer:

x2 + (y + 8)2 = 36

Step-by-step explanation:

:) took the test

The equations which represent circles that have a diameter of 12 units and a center that lies on the y-axis are x² + (y – 3)² = 36 and x² + (y + 8)² = 36.

What is the Standard form of a Circle?

Standard form of a circle is given by the equation,

(x - h)² + (y - k)² = r²

where, (h, k) is the center of the circle and r is the radius of the circle.

Given that,

A circle has a diameter of 12 units.

So radius = 12 / 2 = 6 units

Center of the circle lies on the Y axis.

So the x coordinate of the center of the circle will be 0.

So, in (h, k), h = 0

So the equation will be of the form,

(x - 0)² + (y - k)² = 6²

x² + (y - k)² = 36

Hence the options are x² + (y – 3)² = 36 and x² + (y + 8)² = 36.
