Answer:
112
Step-by-step explanation:
This is a cyclic quadralterial. A cyclic quadralterial is a quadralterial that is inscribed in a circle where all the point or vertices of the quadralterial touches the circle circumference. Opposite angles in a cyclic quadralterial are supplementary.
Angle R and Angle QPS or P is supplementary since they are opposite angle.
Substitute 68 for R
So the answer is 112
