I need to use the Pythagorean Theorem to find X. I don’t know how to do that!!

Answers

Answer 1

Answer:

17) x=8

18) [tex]x=\sqrt{189}[/tex] or [tex]x= 3\sqrt{21}[/tex]

Step-by-step explanation:

So the rule is [tex]a^{2} +b^{2} =c^{2}[/tex], "c" being the hypothenuse, or the long line that is opposite to the right angle.

17) We know that both values of x are equal to each other, which makes everything 10x easier!

[tex]x^{2} +x^{2} =(8\sqrt{2}) ^{2}[/tex]

(by the way we know the x values are our a and b values because they are legs! the way I like to remember the legs is that they are connected to the right angle box, and therefore support the hypothenuse)

simplify (╥︣﹏╥)

[tex]2x^2=8^2(\sqrt{2} )^{2}[/tex]

[tex]2x^2=64(2)[/tex]

[tex]2x^2=128[/tex]

[tex]x^{2}= 128/2[/tex]

[tex]x^{2} =64[/tex]

x=8

18) Just pretend that the flipped triangle doesn't exist. It's parallel to the other triangle with values on it, and basically servers no purpose other than being parallel to the sister triangle :)

Anyways, since we know the hypothenuse (15) but we don't know one of our leg values (x), we're going to change our equation a bit!

[tex]c^{2} - b^{2} = a^{2}[/tex]

It doesn't matter if you put the one leg value in a or b, just as long as you stick to that same equation you started with the entire time!

[tex]15^{2} -6^{2} =x^{2}[/tex]

[tex]225-36=x^{2}[/tex]

[tex]x^{2} =189[/tex]

[tex]x=\sqrt{189}=3\sqrt{21}[/tex]

The more you do these, the easier they'll get, so don't worry!

Given KW is perpendicular to JO, JP is perpendicular to KO, KN intersects with JP=Q. Prove that triangle OKW ~ triangle OJP

Answers

Answer:

Proved

Step-by-step explanation:

m∠JPO = 90 = m∠OWK, and angle O is common between both triangles [reflexive property]. Therefore by Rule AA, ΔOKW~ΔOJP

Triangle OKW similar to triangle OJP by angle-angle or AA or ΔOKW ~ ΔOJP by AA.

What is the similarity law for triangles?

It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.

Please refer to the attached picture for the diagram.

We have:

KW is perpendicular to JO, JP is perpendicular to KO.

KN intersects with JP=Q.

From the figure:

Angle JPO =Angle OWK = 90 degrees

By using the reflexive property:

Angle O = Angle O

Thus, triangle OKW similar to triangle OJP by angle-angle or AA or ΔOKW ~ ΔOJP by AA.

Tim wants to buy several pairs of jeans. He compares the prices at a store in his neighborhood and at an online store. He finds that a pair of jeans costs $24 at the local store. If he buys online, each pair would cost $22, and he would have to pay a shipping fee of $6 per order.

Answers

Answer:

2 orders

Step-by-step explanation:

Step one:

given data

The local store sells at $24 per pair of jeans

Cost = $24

The online store sells at $22 per pair plus a shipping fee of $6 per order

let the number of orders be x

Cost= 22+6x

For 1 order

the online store will cost

Cost= 22+6*1

Cost= 22+6

Cost= $28

For 2 orders

The local shop cost

Cost= 24*2= $48

The online store will cost

Cost= 22+6*2

the online store will cost

Cost= 22+12

Cost= $34

Hence Tim should place at least 2 orders if he wants to buy online

Answer:

# of orders is 2 ORDERS!!!

Lines N and Pare parallel. Angle M measures 126 degrees. Find the measure of angle Q.

Step-by-step explanation:

Using the picture given, because these are parallel lines broken by a transversal, we can say the following

M=A=Q=F

B=C=D=G

Since, for example, M and C are the same line, we can say that M+C=180 and so on.

M=Q

Q= 126°

ty-qy+p=r solve for y

Answers

Answer:

[tex]\huge\boxed{y= \frac{r-p}{t-q}}[/tex]

Step-by-step explanation:

In order to solve for y in this equation, we can algebraically manipulate it to isolate y one one side of the equation.

Step 1: Subtract [tex]p[/tex] from both sides of the equation.

[tex]ty - qy + p - p = r[/tex] [tex]ty-qy=r - p[/tex]

Step 2: Factor out the common term [tex]y[/tex] from the left side

[tex]y( t-q ) = r-p[/tex]

Step 3: Divide both sides by [tex]t-q[/tex]

[tex]\frac{y(t-q)}{t-q} = \frac{r-p}{t-q}[/tex] [tex]y = \frac{r-p}{ t-q}[/tex]

Hope this helped!

3. The Statue of Liberty is 305 feet tall. Lisa has a replica that is 9 inches tall and the

length of the right arm holding the torch isi inches. How tall is the actual right arm

holding the torch?

Answers

Answer: 33.9 inches

Step-by-step explanation:

Assuming you meant to write that the length of the right arm holding the torch is 1 inch:

The statue is 305 feet tall and the replica is 9 inches tall.

If the replica's right arm is 1 inch, the actual arm will be:

= 1 * 305/9

= 33.9 inches

If right arm of replica was not 1 inch, use this answer as reference.

Steve’s baseball team played 33 games and won 15 of them. What percent did the team win? *

Answers

Answer:

Approximately 45%.

Step-by-step explanation:

We know that Steve's team played in total 33 games. Out of the 33, they won 15 of them.

So, as a fraction of the total won over the total games, we can write:

[tex]\displaystyle\frac{15}{33}[/tex]

So, by dividing, the percent the team won is:

[tex]\displaystyle\frac{15}{33}=0.\overline{45}=0.454545...\approx0.45=45\%[/tex]

The team won approximately 45% of its games.

Sarah‘s mother is 28 years older than Sarah is their combined age is 50 how old is Sarah how old is Sarah‘s mom

Answers

Answer: 39 years old

Step-by-step explanation:

First find Sarah's age.

It is said that their ages sum up to 50 and that Sarah's mother is 28 years older than Sarah.

Assume Sarah's age is x.

Sarah's mother's age would be: x + 28.

The expression would therefore be:

x + (x + 28) = 50

2x + 28 = 50

2x = 50 - 28

x = 22/2

x = 11

Sarah is 11 which means her mom is:

= 11 + 28

= 39 years old
