Your answer would be 5.
Scale factor= 5 because 45/9= 5
Since it’s a dilation you use the scale factor to find x
So 25/5= 5

Answer:

5

Step-by-step explanation:

As we can see they are similar triangles then

the ratio of the corresponding sides are equal then

x /25 = 9/45

x = 25 * 1/ 5

x = 5

Hope it will help :)

(02.02)Line segment EF is shown on a coordinate grid: A coordinate plane is shown. Line segment EF has endpoints negative 3 comm
Andrew [12]

Answer:

E'F' and EF are equal in length

Step-by-step explanation:

we have

The coordinates of point E(-3,2) and F(-1,2)

we know that

The rule of the reflection across the x-axis is

(x,y) ------> (x,-y)

so

Applying the rule of reflection across the x-axis

E(-3,2) -------> E'(-3,-2)

F(-1,2) --------> F'(-1,-2)

using a graphing tool

see the attached figure to better understand the problem

therefore

E'F' and EF are equal in length

1.

Use this rule: √ab = √a√b

√12√x^2

Simplify √12 to 2√3

2√3√x^2

Simplify √x^2 to x

2√3x^2

3.

Multiply the numerator and denominator by the conjugate.

Please answer this for me pleaseeeee

Answer:

\Huge\boxed{x=71.9}

Step-by-step explanation:

Hello There!

Once again we are going to use trigonometry to solve for x

Here are the <u>Trigonometric Ratios</u>

sin = opposite divided by hypotenuse

cos = adjacent divided by hypotenuse

tan = opposite divided by adjacent

we need to find x and we are given its opposite side length (58) and the adjacent side length (19)

this corresponds with tangent so once again we will be using tangent to solve for x

Looking at tangent we see that its equal to opposite divided by adjacent so we create an equation

tan(x)=\frac{58}{19}\\\frac{58}{19} =3.052631579

now we have

tan(x)=3.052631579

Once again we need to get rid of the tan

to do so we take the inverse of tan ( tan^-1) and apply it to each side

arcsin^-^1(tan(x))=x\\arcsin^-^1(3.052631579)=71.86191784

finally we round to the nearest tenth

we're left with x = 71.9

Ave had a rectangular garden that is shown below. The garden's area is 32 square feet. The length of the width is 4 feet. What i
Arlecino [84]

Answer:

The length of Ave's garden is 8 feet.

Step-by-step explanation:

The area of a rectangle can be calculated by:

              A = l × w

Where; A represents the area, l the length and w, width.

Thus from the question,

          32 =  l × 4

           l = 32 /4

           l = 8

Therefore, the length of the garden required is 8 feet.
