we know that
The triangles ced and bea are similar and ba and cd are corresponding side lengths of the two similar triangles

scale factor= measure cd/measure ba
scale factor=5/2
measure ba=6 units
measure cd=measure ba*scale factor
measure cd=6*(5/2)-------> 15 units

the answer is
cd is equal to 15 units
