Answer:

  x = 8

Step-by-step explanation:

The value of x can be found by equating the associated angle with its vertical angle. That vertical angle is the difference between the one marked 18° and the right angle.

  ∠ZJW = ∠HJZ -∠WJZ = 90° -18° = 72°

  ∠GJL ≅ ∠ZJW

  (9x)° = 72°

  x = 72/9 = 8
