What is m∠BCD? A. 82 degrees B 168 degrees C. 192 degrees D. 220 degrees

m∠BCD = 82°

Option A

Step-by-step explanation:

The opposite angles of quadrilateral inscribed in a circle are supplementary.

i.e m∠A +m∠C = 180°

or, m∠BAD + m∠BCD= 180°

or, 98° + m∠BCD = 180°

or, m∠BCD = 180°-98°

or,m∠BCD = 82°
