There is a theorem for inscribed quadrilaterals in a circle. This theorem states that: "<span>Opposite angles in any quadrilateral inscribed in a circle are supplements of each other".
In other words, the sum of each two opposite angles in a quadrilateral inscribed in a circle is 180.
Based on the above:
measure angle O + measure angle Q = 180
measure angle R + measure angle P = 189
Therefore:
measure angle P = 180 - measure angle R</span>

Answer:
The answer is A
Step-by-step explanation:
Supplementary angles are angles which add up to 180°
∠1 and ∠3 add up to 180°, so they are supplementary.
