I believe the correct answers are:

<span>UV = 14 ft and m∠TUV = 45°</span>
<span>ST = 20 ft, UV = 14 ft, and m∠UST = 98°

Or, in other words, Options A and D.

Answer:-The first and fourth information can be the additional information to show that ΔSTU ≅ ΔVTU by SAS.


Explanation:-

Given :- In ΔSTU and ΔVTU

SU=14ft , VT=20 ft ,m∠SUT=45° and m∠TUV=98°

The given additional information:-

1.UV = 14 ft and m∠TUV = 45°

Then SU=UV = 14 ft   [given]

m∠TUV =m ∠SUT=45°  [given]

TU=TU [Reflexive property]

⇒ΔSTU ≅ ΔVTU [SAS congruence postulate]

2. TU = 26 ft

⇒ Not enough information to prove triangles congruent.

3. m∠STU = 37° and m∠VTU = 37°

⇒m∠STU = 37° =m∠VTU = 37° [Transitive property]

And TU=TU[Reflexive property]

But we need one more information to prove them congruent.

4. ST = 20 ft, UV = 14 ft, and m∠UST = 98°

ST = 20 ft=TV  [given]

m∠UST = 98°=m∠UVT [given]

TU=TU  [Reflexive property]

⇒ΔSTU ≅ ΔVTU [ SAS postulate]

5. m∠UST = 98° and m ∠TUV = 45°

m∠UST = 98°=m∠UVT [given]

TU=TU   [Reflexive property]

m ∠TUV = 45°=∠TUS [given]

⇒ΔSTU ≅ ΔVTU  [AAS congruence theorem]

Thus the first and fourth information can be the additional information to show that ΔSTU ≅ ΔVTU by SAS.

The sector COB is cut from the circle with center O. The ratio of the area of the sector removed from the whole circle to the ar
mafiozo [28]

Answer:

Ratio = \frac{R^2 - r^2 }{ r^2}

Step-by-step explanation:

Given

See attachment for circles

Required

Ratio of the outer sector to inner sector

The area of a sector is:

Area = \frac{\theta}{360}\pi r^2

For the inner circle

r \to radius

The sector of the inner circle has the following area

A_1 = \frac{\theta}{360}\pi r^2

For the whole circle

R \to Radius

The sector of the outer sector has the following area

A_2 = \frac{\theta}{360}\pi (R^2 - r^2)

So, the ratio of the outer sector to the inner sector is:

Ratio = A_2 : A_1

Ratio = \frac{\theta}{360}\pi (R^2 - r^2) : \frac{\theta}{360}\pi r^2

Cancel out common factor

Ratio = R^2 - r^2 : r^2

Express as fraction

Ratio = \frac{R^2 - r^2 }{ r^2}

Find the value of x.
timofeeve [1]

Answer:

<h3>x = 83°</h3>

Step-by-step explanation:

{x}^{o}  + {75}^{o}  +  {97}^{o}  +  {105}^{o}  =  {360}^{o}  \\  {x}^{o}  +  {277}^{o}  =  {360}^{o}  \\  {x}^{o}  =  {360}^{o}  -  {277}^{o}  \\  {x}^{o}  =  {83}^{o}  \\
