A semicircle has AB as the endpoints of its diameter, and AB=80. Points C and D are on the circumference of the semicircle such that AD=BC=40. What is the length of DC?

  • geometry -

    Since the radius is equal to the given chords, the central angle is 60 degrees.
    (An inscribed hexagon has sides equal to the radius)

    So, DC is also 40
