Answer:

  • B. 132°

Step-by-step explanation:

Find the measure of arc BD

  • m∠A = 1/2(arc BC - arc BD)
  • 2*36° = 150° - arc BD
  • arc BD = 150° - 72° = 78°

Find the measure of arc DC

  • arc BD + arc BC + arc DC = 360°
  • arc DC = 360° - (150° + 78°) = 360° - 228° = 132°

Correct choice is B
