Question

The diameter of circle C is 18 cm. Chord AD is the same length as a radius. What are the measures of angles BDA and DBA

Answer 1

Do you have the diagram?

Answer 2

sorry hold up

Answer 3

Ok what is the corresponding angles of the circle?

Answer 4

You don't necessarily need a diagram

Answer 5

sorry i dont really know:(

Answer 6

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.
