Answer:

  • D) 72°

Explanation:

Sum of angles 7 and 8 is 180° as they are supplementary

Angles 7 and 3 are corresponding angles and they measure same as per property of corresponding angles, therefore:

  • m∠3 = m∠7
  • m∠7 = 180° - m∠8 = 180° - 108° = 72°
  • So m∠3 = 72°

Option D is correct
