The matrix equation that represents this situation is

\left[\begin{array}{ccc}3&2&0\\1&0&4\\3&1&1\end{array}\right]*\left[\begin{array}{ccc}x\\y\\z\end{array}\right]=\left[\begin{array}{ccc}13.50\\16.50\\14.00\end{array}\right]

Use technology to find the inverse of matrix A:

A^{-1}=  \left[\begin{array}{ccc}-\frac{2}{5}&-\frac{1}{5}&\frac{4}{5}\\
\frac{11}{10}&\frac{3}{10}&-\frac{6}{5}\\\frac{1}{10}&\frac{3}{10}&-\frac{1}{5}\end{array}\right]

Multiplying A inverse by B, we get the solution matrix

Reptile [31]

Answer:

∠ZVW= 45

∠ZWV = 31

x=1

Step-by-step explanation:

Properties of a Parallelogram ( including diagonals )

Diagonals of a parallelogram bisect each other.

The diagonals are cut into two equal parts

Opposite angles are congruent

Given this information we need to find x, ∠ZVW and ∠ ZWV

First lets find x

Like stated previously diagonals cut each other into two equal parts

That being said segment WZ ≅ segment ZY

Knowing this we create an equation

2z-1=1

step 1 add 1 to each side

-1 + 1 cancels out

1 + 1 = 2

now we have 2x = 2

step 2 divide each side by 2

2x/2=x

2/2=1

we're left with x = 1

Now lets find ∠ZVW

∠ZVW and ∠ZXY happen to be opposite angles ( opposite angles are congruent )

This means that because ∠ZXY = 45 ∠ZVW also = 45

Now lets find ∠ZWV

∠ZWV and ∠XYZ happen to be opposite angles ( like stated previously, opposite angles are congruent)

So because ∠XYZ = 31 ∠ZWV also = 31
