Use the Pythagorean theorem to find the length of the leg in the triangle shown below 12 15
Norma-Jean [14]

Answer:

9 = x (assuming 15 is the hypotenuse)

Step-by-step explanation:

15^2 = 12^2 + x^2

225 = 144 + x^2

subtract 144 from both sides

81 = x^2

square root both sides

9 = x

After how many years are the salaries offered by Company A and Company B the same?
iren2701 [21]

Answer:

Step-by-step explanation:

24,000 = 24 thousands

30,000 = 30 thousands

3,000 = 3 thousands

2,4000 = 2.4 thousands

"x" years

24 + 3x = 30 + 2.4x

3x - 2.4x = 30 - 24

0.6x = 6

x = <em>10 years</em>

This is a 2 part question. Need help with both questions please! Use the triangle for both parts of the question. Click on the f
ollegr [7]

Answer:

Part A) Option A. QR= 3 cm

Part B) Option B. SV=6.5 cm

Step-by-step explanation:

step 1

<u>Find the length of segment QR</u>

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

so

In this problem Triangle QRW and Triangle QSV are similar by AA Similarity Theorem

so

\frac{QR}{QS}=\frac{QW}{QV}

we have

QS=9\ cm ---> because S is the midpoint QT (QS=TS)

QW=2\ cm --->because V is the midpoint QU (QW+WV=VU)

QV=6\ cm --->because V is the midpoint QU (QV=VU)

substitute the given values

\frac{QR}{9}=\frac{2}{6}

solve for QR

QR=9(2)/6=3\ cm

step 2

Find the length side SV

we know that

The <u><em>Mid-segment Theorem</em></u> states that the mid-segment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this mid-segment is half the length of the third side

so

In this problem

S is the mid-point side QT and V is the mid-point side QU

therefore

SV is parallel to TU

and

SV=(1/2)TU

so

SV=(1/2)13=6.5\ cm
