Answer:

141°

Step-by-step explanation:

It's an octagon so the Sum of interior angles is: (8-2)×180=1080

5x+133+16+126+162-12+30=5x+455=1080

5x=625

x=125

x+16=141

Apply angle sum property

  • x+162+x-12+x+30+x+133+x+16+126=1080
  • 5x+455=1080
  • 5x=1080-455
  • 5x=625
  • x=125

So

  • x+16
  • 125+16
  • 141
