Given parallelogram FGHI determine the missing information

Don’t answer with one answer, blank or ridiculous answer please this is serious

Answers

Answer:

y = 3 cm and x = 2.5 cm

Step-by-step explanation:

As we can see it is a parallelogram so

y = 3 cm (being opposite sides of parallelogram)

Now while calculating the diagonal we can use the Pythagoras relation. i.e

perpendicular (p) = 4 cm (IH)

Base (b) = 3 cm (FI)

Hypotenuse (h) = FH = ?

We know by using Pythagoras theorem

h = √ p² + b²

= √ 4² + 3²

= √ 25

= 5 cm

Here we got FH = 5 cm

so the value of x will be 2.5 cm as the diagonal bisects.

Hope it will help :)

How can we get system B for system A?

And

Are the systems equivalent?

Answers

Answer: Subtract the equations in system A.

=============================================================

Explanation:

The first equation of each system is the same, so we'll try to transform the second equation of system A into the second equation of system B.

There are probably a number of ways to do this, but the quickest way that I can see is to subtract the equations of each system.

For system A, notice how the x terms line up and subtract to 5x-4x = 1x = x. In that same system, we have the y terms subtract to y minus (-7y) = y-(-7y) = y+7y = 8y

So far we have x and 8y as the results. So the left side is x+8y, which matches with the x+8y in the second equation of system B. So far so good.

Now we subtract the values on the right hand sides of each equation of system A. We get 3-8 which turns into -5, which also matches with the -5 in the second equation of system B.

Overall, subtracting the two equations of system A leads to x+8y = -5, which is the second equation of system B.

Question 27 options:

270° counterclockwise rotation

Reflection across the y-axis

90° clockwise rotation

90° counterclockwise rotation

Answers

Answer:

90 degree counterclockwise rotation

Step-by-step explanation:

After a 90° counterclockwise rotation, we get the required quadrilateral A'B'C'D'.

Hence the fourth option is correct.

The rotation of axes refers to a transformation in which the coordinate axes in a coordinate system are rotated to form new axes.

When we rotate the quadrilateral ABCD about 90 degrees counterclockwise,

The new position of vertices be,

A ⇒ B'

B ⇒ C'

C ⇒ D'

D ⇒ A'

Hence,

After this rotation, we get the required quadrilateral A'B'C'D' as shown in the figure.

Hence,

After 90° counterclockwise rotation we get such a triangle.

If triangle ACD is similar to triangle ABE, find the value of x?

Answers

Upload a photo please

The value of x and y from the given figure is 2.1 units and 4.5 units.

Given that, triangle ACD is similar to triangle ABE.

What are similar triangles?

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Here, AB=3, AC=5, BE=x, AE=y, ED=3 and CD=3.5

AD=AE+ED

AD=y+3

Now, AB/AC = AE/AD = BE/CD

So, 3/5 = y/(y+3) = x/3.5

⇒ 3/5 = x/3.5

⇒ 3×3.5=5x

⇒ 5x=10.5

⇒ x=10.5

⇒ x=2.1

3/5 = y/(y+3)

⇒3y+9 =5y

⇒2y =9

⇒y =4.5

Therefore, the value of x and y from the given figure is 2.1 units and 4.5 units.

The equation is a proportional equation and can be represented as y = kx

k is the constant of proportionality

k = y/x

Using (2, 4),

k = 4/2 = 2

To find the equation, substitute k = 2 into y = kx

Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 5 cm, 9 cm, 12 cm, and 15 cm

Answers

Answer:

Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.

Step-by-step explanation:Pythagorean Theorem: According to this theorem the result obtained by squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.

Hypotenuse = h

Altitude = l

Base = b

l²+b²=h²

Here 6²=36

9²=81

12²=144

15²=225

From the above it is clear that

81+144=225

⇒9²+12²=15²

Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
