AC and DB are chords that intersect at point H.

valentinak56 [21]

Answer:

16 units

Step-by-step explanation:

see the attached figure to better understand the problem

Applying the Intersecting Chords Theorem

we have that

$AH*HC=DH*HB$

substitute the given values

$(20-x)(x)=(x+4)(12-x)$

$20x-x^2=12x-x^2+48-4x$

Simplify

$20x=8x+48$

$20x-8x=48$

$12x=48$

$x=4$

Find out the length of segment DB

$DB=DH+HB$

$DB=(x+4)+(12-x)=16\ units$

<em>Note</em> In this problem it was not necessary to determine the value of x to calculate the DB segment.

Anyway, the calculation was done for didactic purposes.
