Answer:

AD = 9 cm

Explanation:

Recognize all of the triangles are 30°-60°-90° triangles that have side ratios of 1 : √3 : 2. That is, the longest side is double the length of the shortest side.

CB = 2(DB)

DB = CB/2 = (6 cm)/2 = 3 cm

AB = 2(CB)

AB = 2(6 cm) = 12 cm

AD +DB = AB

AD +3 cm = 12 cm

AD = 9 cm . . . . . . . . . . subtract 3 cm
