A) \[\frac{\pi }{2}\]
B) \[\frac{\pi }{3}\]
C) \[\frac{\pi }{4}\]
D) \[\frac{\pi }{6}\]
Correct Answer: C
Solution :
Here the centre \[0\,(0,0)\]. So ?m? of OQ is \[\frac{4}{3}\]and ?m? of OR is \[\frac{-3}{4}\], \ \[\angle QOR=\frac{\pi }{2}\] Hence \[\angle QPR=\frac{1}{2}\times \frac{\pi }{2}=\frac{\pi }{4}\].You need to login to perform this action.
