Asked by ARI33

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?
Answered by Steve
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
