Given: Circle O, diameter, marked perpendicular, Chord BC= 10, find x?
- KrishnamurthyLv 71 year ago
OA^2 + OC^2 = x^2 (or AC^2)
AC = BC
Since BC = 10, x = 10

The long chord is bisected into BC and AC. So they have the same length. You said BC = 10, so AC would be the same length.
x = 10 units
P.S. If you meant that chord *AB* was 10, then x would be 5.
