Step-by-step explanation:

(6)

The opposite sides of a parallelogram are congruent , so

10x + 6 = 4x + 18 ( subtract 4x from both sides )

6x + 6 = 18 ( subtract 6 from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

--------------------------------------------------------

(7)

The opposite angles of a parallelogram are congruent , so

9z - 42 = 5z + 8 ( subtract 5z from both sides )

4z - 42 = 8 ( add 42 to both sides )

4z = 50 ( divide both sides by 4 )

z = 12.5

------------------------------------------------------------

(8)

The sum of the interior angles of a quadrilateral = 360°

Subtract the sum of the 3 given angles from 360° for 4th angle

4th angle = 360° - (49 + 111 + 133)° = 360° - 293° = 67°

-----------------------------------------------------------

(9)

Opposite sides are congruent , so

XZ = WY = 22

YX = ZW = 31
