Answer:

See below ~

Explanation:

7

  • ∠EOF = 180 - 126
  • ∠EOF = 54°

  • ∠BOF = ∠COE
  • ∠COE = 126°
  • ∠COE = 2∠DOE
  • ∠DOE = 126/2
  • ∠DOE = 63°

  • ∡DEF = ∠DOE + ∠EOF
  • ∡DEF = 63° + 54°
  • ∡DEF = 117°

8

  • ∠DOE = 63°

9

  • ∠BOC = ∠EOF (vertically opposing angles)
  • ∠BOC = 54°

  • ∠BOD = ∠BOC + ∠COD
  • ∠BOD = 54° + 63°
  • ∠BOD = 117°

10

  • ∠BDF (major angle) = ∠BOC + ∠COD + ∠DOE + ∠EOF
  • ∠BDF = 2∠BOC + 2∠COD
  • ∠BDF = 2(54) + 2(63)
  • ∠BDF = 108 + 126
  • ∠BDF = 234°

  • ∡BDF = ∠BDF (major angle)
  • ∡BDF = 234°

  • The 5 radii are : OB, OC, OD, OE, OF
