Given: SR bisects angle TSQ angle T is congruent to angle Q prove: triangle RTS is congruent to RQS
yan [13]

Triangle RTS is congruent to RQS by AAS postulate of congruent

Step-by-step explanation:

Let us revise the cases of congruence  

  • SSS  ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
  • SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and  including angle in the 2nd Δ
  • ASA ⇒ 2 angles and the side whose joining them in the 1st Δ  ≅ 2 angles and the side whose joining them in the 2nd Δ
  • AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles   and one side in the 2nd Δ
  • HL ⇒ hypotenuse leg of the 1st right Δ ≅ hypotenuse  leg of the 2nd right Δ

∵ SR bisects angle TSQ ⇒ given

∴ ∠TSR ≅ ∠QSR

∴ m∠TSR ≅ m∠QSR

∵ ∠T ≅ ∠Q ⇒ given

∴ m∠T ≅ m∠Q

In two triangles RTS and RQS

∵ m∠T ≅ m∠Q

∵ m∠TSR ≅ m∠QSR

∵ RS is a common side in the two triangle

- By using the 4th case above

∴ Δ RTS ≅ ΔRQS ⇒ AAS postulate

Triangle RTS is congruent to RQS by AAS postulate of congruent

In a random sample of fivefive microwave​ ovens, the mean repair cost was ​$75.0075.00 and the standard deviation was ​$13.0013.
Radda [10]
<h2>Answer with explanation:</h2>

As per given , we have

Sample size : n= 5

Degree pf freedom = : df= 5-1=4

\mu=\$75.00

\sigma=\$13.00

Significance level for 90% confidence = \alpha=1-0.90=0.1

Using t-value table , t-critical value for 90% confidence:

t_{\alpha/2, df}=t_{0.05, 4}=2.132.

Margin of error of \mu: E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\(2.132)\dfrac{13}{\sqrt{5}}=12.3949720129\approx12.39

Interpretation : The repair cost will be within $12.39 of the real population mean value \mu 90% of the time.

NO LINKS!!!<br><br>QRSTU ~ FGCDE. Find FG, CD, and EF. ​
arsen [322]

Answer:

See below ~

Step-by-step explanation:

Given :

<u>QRSTU ~ FGCDE</u>

Finding the scale factor :

  • Take two corresponding sides in proportion
  • RS : GC
  • 40 : 12
  • <u>10 : 3</u>

Applying the scale factor to find the missing sides :

- FG :

  • QR : FG = 10 : 3
  • 30/FG = 10/3
  • FG = 30/10 x  3
  • FG = 3 x 3
  • <u>FG = 9</u>

- CD :

  • ST : CD = 10 : 3
  • 40/CD = 10/3
  • CD = 40/10 x 3
  • CD = 4 x 3
  • <u>CD = 12</u>

- EF :

  • UQ : EF = 10 : 3
  • 30/EF = 10/3
  • EF = 30/10 x 3
  • EF = 3 x 3
  • <u>EF = 9</u>
