Points A, B, C, and D lie on circle M. Line segment BD is a diameter. The measure of arc CD equals the measure of arc DA. Circle M is shown. Line segment B D is a diameter. LIne segments E M and A M are radii. Lines are drawn from points C and A to point D to form chords. A line is also drawn from point C to point A. Angle C M A is 90 degrees. Arcs C B and B A are congruent. What is the measure of angle ADM? 22.5° 30.0° 45.0° 67.5°
