Answer:

  • m∠A = 79°
  • m∠B = 112°

Explanation:

We have cyclic quadrilateral as all vertexes are on the circle.

As per property of cyclic quadrilateral, each pair of opposite angles are supplementary.

As we know supplementary angles add up to 180°.

  • m∠A + m∠C = 180° ⇒ m∠A = 180° - 101° = 79°
  • m∠B + m∠D = 180° ⇒m∠B = 180° - 68° = 112°
