    Se below.

    Step-by-step explanation:

    The Chord Intersection Theorem:

    If 2 chords of a circle are AB and CD and they intersect at E, then

    AE * EB = CE * ED.

    Problem.

    Two Chords AB and CD intersect at E. If AE = 2cm, EB = 4 and CE = 2.5 cm, find the length of ED.

    By the above theorem : 2 * 4 = 2.5 * ED

    ED = (2 * 4) / 2.5

    = 3.2 cm.
