What is the measure of arc BD in the diagram below?

Answer 1

isnt it 20 as well?

Answer 2

I don't think it is.

Answer 3

The angle formed by two secants drawn to a circle from an exterior point has measure half the difference of the two intercepted arcs. That would be half the difference of the far arc and the near arc.
