Answer:

  • m∠1 = mCD = 40°
  • m∠2 = 1/2(mAB) = 1/2*30° = 15°
  • m∠3 = 1/2(mED) = 1/2*50° = 25°
  • m∠4 = 1/2(mAB + mDE) = 1/2(30°+50°) = 40°
  • m∠6 = m∠OEG - m∠DEG = 90° - 1/2(mDE) = 90° - 25° = 65°
  • m∠7 = 1/2(mCD + mDE) = 1/2(40°+50°) = 45°
  • m∠8 = 1/2(mCD + mDE - mAB) = 1/2(40° + 50° - 30°) = 30°
  • m∠10 = 1/2mAE = 1/2(180° - mDE) = 1/2(180° - 50°) = 65°
