Question

I Really need help! I don’t understand this! Will give 100 points!

Answer 1

Answer:

All pair COMBINATION are supplementary (Opposite)

Step-by-step explanation:

According to theorem about inscribed quadrilateral

• The opposite interior angles of an inscribed quadrilateral are supplementary .
• I.e there sum is equal to 180°

<O+<Q=180

<P+<R=180

Answer 2

Answer:

m∠O and m∠Q are supplementary

m∠P and m∠R are supplementary

Step-by-step explanation:

Cyclic quadrilateral:  a quadrilateral drawn inside a circle where every vertex of the quadrilateral touches the circumference of the circle.

Theorem:  Opposite angles in a cyclic quadrilateral add up to 180°

Supplementary angles are two angles whose measures sum to 180°

Therefore, the opposite angles in a cyclic quadrilateral are supplementary:

m∠O + m∠Q = 180°

m∠P + m∠R = 180°
