Answer:
60°
Step-by-step explanation:
We are given that DC = AB
PD, PC, AP and PB are the radius of circle.
In ΔAPB and ΔCPD
AP=CP (Radius of circle)
PB=PD (radius of circle)
DC=AB(Given)
So, By SSS property of congruence
ΔAPB≅ ΔCPD
Now we are given that ∠DPC = 60°
∠BPA=x
So, ∠DPC=∠BPA (ΔAPB≅ ΔCPD)
∠DPC=∠BPA =x= 60°
Thus the value of x is 60°
Hence Option B is correct.
