Answer:

  x = 8

  there is no ∠1

Step-by-step explanation:

The angle sum theorem tells you ...

  ∠XYW +∠WXZ = ∠XYZ

  70° +(5x -4)° = 106°

  5x = 40 . . . . . . . . . . . divide by °, subtract 66

  x = 8 . . . . . . . . . divide by 5

  ∠WYZ = 36° . . . . . . . the difference between 70° and 106°
