Given the pair of triangles are similar find the unknown length of the sides labeled with a variable
MArishka [77]

Answer:

The answer is below

Step-by-step explanation:

The question is not complete. Let us assume the following:

Let us assume triangle ABC is a right angled triangle with side AB = 24, AC = 32 and the hypotenuse BC = 40.  Triangle PQR is a right angled triangle similar to triangle ABC with side PQ = 27,  PR= b and the hypotenuse QR = a.

Answer:

Two triangles are said to be similar if they have proportional angles or proportional sides that is they have the same shape. For similar triangles, the ratio of their corresponding side are the same.

Given that triangle ABC is similar to triangle PQR, therefore:

\frac{AB}{AC}=\frac{PQ}{PR}\\  Substituting:\\\frac{24}{32}=\frac{27}{b}\\cross\ multiplying:\\b=\frac{27*32}{24}\\ b=36

\frac{AB}{BC}=\frac{PQ}{QR}\\  Substituting:\\\frac{24}{40}=\frac{27}{a}\\cross\ multiplying:\\a=\frac{27*40}{24}\\ a=45

4w^2+49=-28w solve for w<br><br> plz answer
boyakko [2]

Move all terms to one side

4w^2 + 49 + 28w = 0

Rewrite 4w^2 + 49 + 28w in the form a^2 + 2ab + b^2, where a = 2w and b = 7

(2w)^2 + 2(2w)(7) + 7^2 = 0

Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2

(2w + 7)^2 = 0

Take the square root of both sides

3w + 7 = 0

Subtract 7 from both sides

2w = -7

Divide both sides by 2

<u>w = -7/2</u>

Find the scale factor where the pre-image is the small triangle and the image is the large triangle.
Oduvanchick [21]

Answer:

The scale factor is \frac{9}{7}

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

so

\frac{18}{14}=\frac{27}{21}=\frac{9}{7}

therefore

The scale factor is 9/7

Find the value of x

The value of x is equal to  

\frac{x}{28}=\frac{9}{7}

x=28(\frac{9}{7})=36\ units
