Answer:
sum of all angle at a point is 360 then
Step-by-step explanation:
115+95+7+2x+3x=360
5x+217=360
5x=143
x=28.6
AOD=7+2x+3x
AOD=7+57.2+85.8
AOD=143+7
AOD=150
BOC=2x
BOC=57.2

∠ AOB + ∠ BOC + ∠ COD + ∠DOE + ∠ EOA = 360°
3x° + 2x° + 7° + 115° + 95° = 360°
5x° + 217° = 360°
5x° = 360° - 217°
5x° = 143°
x° = 143° / 5°
x° = 28.6°
∠ AOD = ∠ AOB + ∠ BOC + ∠ COD
= 3x° + 2x° + 7°
= 3(28.6)° + 2(28.6)° + 7°
= 85.8° + 57.2° + 7°
∠ AOD = 150°
∠ BOC = 2x°
= 2(28.6)°
∠ BOC = 57.2°
