In the circle below, if arc AB is congruent to arc CD, chord AB = 16x - 2 and chord CD = 14x + 8, find x.

Answer:
d. x = 5
Step-by-step explanation:
Chords that subtend congruent arcs are congruent.
Chord lengths are the same:
AB = CD
16x -2 = 14x +8
2x = 10 . . . . . . add 2-14x
x = 5 . . . . . . . . divide by 2
