Points B, C, D lie on Circle A. Line segment BD is the diameter of circle A. Measure of arc CB is 54 degrees.

What is the measure of ∠DBC?

54°

36°

27°

63°

Answer 1

Now you have 54 degrees and 180 degrees. You add them together then subtract to find arc CD. Since angle DBC is an inscribed angle. The angle is half of the arc it is intersecting.
