Hi, could someone explain to me the steps I should take to solve the following problem. If radius BE is a perpendicular bisector of chord AC, then what is AB to the nearest tenth? BD is 7cm and DC is 9.

Answer 1

You are obviously looking at some circle diagram that I can't see.

In BE , which is the centre, B or E ?
Where does DC come from?
Where does BD come from ?

All I know so far is that AC is a chord.

Answer 2

One wonders where point D is.
