In the given figure, P,Q,R and S are concylic points, and O is the mid – InterviewSolution

1.	In the given figure, P,Q,R and S are concylic points, and O is the mid-point of the diameter QS. If `angleQPR=25^(@)`, then find `angleSQR`. A. `130^(@)`B. `120^(@)`C. `75^(@)`D. `100^(@)`
Answer» Correct Answer - A Given, `angleQPR=25^(@)`. Since, QS is the diameter, `angleQPS=90^(@)`. `rArr angleSPR = 90-25^(@)=65^(@)` `therefore angleSOR=2 xx 65^(@)=130^(@)`.
