but angle pcb do not lies in triangle bca for applying angle sum property
I applied it in ACB
I don't understand
See...ACB is Triangle in Semi circle?
So it will be 90°
Pca is 110....AcB 90....so we will minus both to find CAB
CAB or PcB
both will be equal since they in alternate segments
OK thank-you so much
You're welcome
