<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.

In AVWX, XV<br> W X and mW<br> - 27°. Find m_X.
SashulF [63]

Answer:

m<X = 126^{o}

Step-by-step explanation:

From the given isosceles triangle, we have;

<W and <V as the base angles

So that,

m<W = m<V = 27 (base angles of an isosceles triangle are equal)

Thus,

m<X + m<V + m<W = 180 (sum of angles in a triangle)

m<X + 27 + 27 = 180

m<X + 54 = 180

m<X = 180 - 54

       = 126

m<X = 126^{o}

EQUATION 10y=80. yes or no. ​
Darya [45]

Answer:

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                                           10*y-(80)=0

 Pull out like factors :

                                10y - 80  =   10 • (y - 8)

           Solve :    10   =  0

This equation has no solution.

A a non-zero constant never equals zero.

  Solve  :    y-8 = 0  

Add  8  to both sides of the equation :  

                     y = 8
