\

From the diagram the angles are $\"\"$ .

\

In a quadrilateral sum of angles measures is $\"\"$ .

\

$\"\"$

\

$\"\"$ (Combine like terms)

\

$\"\"$ (Add: $\"\"$ ) $\"\"$

\

$\"\"$ (Subtract 132 from each side)

\

$\"\"$ (Apply additive inverse property: $\"\"$ )

\

$\"\"$ (Apply additive identity property: $\"\"$ )

\

$\"\"$ (Subtract: $\"\"$ ) $\"\"$

\

$\"\"$ (Divide each side by 3)

\

$\"\"$ (Cancel common terms)

\

$\"\"$ (Divide: $\"\"$ )

\

So, $\"\"$ .

\

$\"\"$ , $\"\"$ , $\"\"$

\

So, the angles measures are $\"\"$ . $\"\"$

\

The value of x is $\"\"$ . The angles measures are $\"\"$ .
