Hello, I partially understand all these questions, but I need help with all of them so I understand it completely so I'll post separately.
This figure shows circle O with chords AC and BD .
m /_ AB =34∘
m /_ CD =34∘
What is BD ?
Enter your answer in the box.
[ ] m
We have triangle BPC
Angle PBC = PCB because they are inscribed angles intercepting the same arc
So....the sides opposite thes angles are equal....so... BP = PC = 8m
And we have triangle APD
For the same reasonas above angle PAD = angle PDA
So.....AP = PD = 6m
So....BD = BP + PD = 8 + 6 = 14 m
