Step-by-step explanation:

  • 90 + (x + 5) + (2x - 2) = 180
  • x + 5 + 2x - 2 = 180 - 90
  • 3x + 3 = 90
  • 3x = 87
  • x = 29

Answer:

29 is the answer.

Step-by-step explanation:

90 + (x + 5) + (2x - 2) = 180

=> 90 + x + 5 + 2x - 2 = 180

=> 93 + x + 2x = 180

=> 3x = 180 - 93

=> 3x = 87

=> 29

Therefore, 29 is the answer.
