Proof:-

In ∆XYZ and ∆VWZ

\because\sf\begin{cases}\sf XZ\cong VZ(Given)\\ \sf YZ\cong WZ(Given)\\ \sf

Hence

∆XYZ\cong∆VWZ(Side-Angle-Side)

<h3>Given:-</h3>

\begin{gathered}\\ \sf\longmapsto XZ≅VZ\end{gathered}

\begin{gathered}\\ \sf\longmapsto YZ≅WZ\end{gathered}

<h3>To prove:-</h3>

⇒△ XYZ≅△ VWZ

<h3>Proof:-</h3>

In △ XYZ&△ VWZ we have,

  • XZ=VZ [Given]
  • ∠XZY=∠VZW [Vertically opposite angles]
  • YZ=WZ [Given]

△ XYZ≅△ VWZ

Hence, Proved by side-angle-side theorem.

Answer:

D.)

Step-by-step explanation:

because when you have numbers inside the parentheses, you have to multiply both of those numbers by the number to the right of the parentheses, not just the X.

Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the lengt
zheka24 [161]

The garden's perimeter = 3+2s+12+s.

The simpler version of the expression = 15+3s.

The variable's frequency in the abbreviated statement is 3.

<h3>Calculation of a triangle's perimeter:</h3>

The triangle's perimeter is equivalent to the sum of its edges, where a, b, and c are its sides.

  • Let the triangle's longest edge be 'a'
  • shorter one to be 's'
  • the opposite side 'b'

With the information provided, the formula will become 'a = 3+2s'

and 'b' is also 12 ft.

Triangle perimeter =the total of its edges

= a + b + s                                                                    

= 3 + 2s + 12 + s

= 15 + 3s

As a result, the garden's perimeter = 3+2s+12+s.

Therefore,the simpler version of the formula is 15+3s.

The variable's coefficient in the abbreviated statement is 3.

Please help with these 3 questions and show all work!
Bas_tet [7]
Question 1:
"Match" the letters
DE are the last two letters of BCDE
The last two letters of OPQR is QR
DE is congruent to QR

Question 2:
Blank 3: Reflexive property (shared side)
Blank 4: SSS congruence of triangles (We have 3 sets of congruent sides)

Question 3:
I'm guessing those two numbers are 7.
Since both are 7, AB and AE are congruent.
We know that all the other sides are congruent because it is given.
We also know that there is a congruent angle in each triangle.
Thus, the two triangles are congruent by SAS or SSS.
(Note: I couldn't prove this without the two "7"s because there is no such thing as SSA congruence)

Have an awesome day! :)
