    Angle DAB is 90; BDA and DBA must add up to 90 as well to make 180. to find BDA: AD=the radius CD and AC are the radius, therefore AD=CD=AC, making it an equilateral triangle. The angle is 60. to find DBA: 180-90-60= 30.

    Somestimes the questions don't provide a diagram and need to rely on the information at hand
