Answer:
D
Step-by-step explanation:
If two chords are equidistant from the centre of the circle, then they are congruent (equal )
Both chords are 3.5 units from the centre, denoted by the dash through both segments from the centre to the chords.
The lower chord has 2 equal segments, denoted by the double dash through each.
lower chord = 5 + 5 = 10 units
then the other chord is 10 units, that is x = 10
