In Fig. 10.101, `P Q` and `P R` are two tangents to a circle with centre `O` . If `/_Q P R=46o` , then `/_Q O R` equals (FIGURE) `67o` (b) `134o` (c) `44o` (d) `46o`

In Fig. 10.101, P Q and P R are two tangents to a circle with centre O . If /_Q P R=46^o , then /_Q O R equals (a) 67^o (b) 134^o (c) 44^o (d) 46^o

In Fig.10.101,PQ and PR are two tangents to a circle with centre O. If /_QPR=460 then /_QOR equals (FIGURE) 67o (b) 134o (c) 44o ( ) 46o

If TP and TQ are the two tangents to a circle with centre O so that /_P O Q=110^@ , then /_P T Q is equal to
