Sagot :
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
