Answer:

4.5 mm

Explanation:

You want the length of AB in similar triangles ACE and BCD, given BD is parallel to AE, and AC=36 mm, ED=9 mm, EC=72 mm.

Proportion

Corresponding segments in the two triangles are proportional, so we have ...

AB/ED = AC/EC

AB/(9 mm) = (36 mm)/(72 mm) = 1/2

AB = (9 mm)(1/2) = 4.5 mm . . . . . multiply by 9 mm

The length of segment AB is 4.5 mm.
