Step-by-step explanation:
BAQ=30
∘
Since AB is the bisector of ∠CAQ
∠CAB=∠BAQ=30
∘
∠CAQ=∠CAB+∠BAQ=60
∘
We can also see that: ∠PAC+∠CAQ=180
∘
So,∠PAC=120
∘
Since AD bisects ∠PAC
So,∠PAD=∠DAC=
2
∠PAC
=60
∘
So,∠DAB=90
∘
And we know that only diameter subtends an angle of 90
∘
on the circle
Hence part (I) is proved
Now we see that ∠CAB & ∠ACBare equal because they share a same side in front on them
