Two rays run from a point O. On the first ray, OA = 6 and OB = 15. On the second ray, OC = 8, and AC is parallel to BD. What is OD?
Correct.This lesson is now marked done.

Not quite.Try again, or ask for a hint.
OA:OB must match OC:OD. Find the ratio from the ray you know completely, then apply it to the other.
