In the diagram below, line segment bc is an altitude of triangle abd. To the nearest whole unit what is the length of cd.

Answer:
A. 23
Step-by-step explanation:
All of the right triangles are similar, so we can write the proportion ...
(short leg)/(long leg) = CD/CB = CB/CA
CD = CB²/CA = 32²/44 ≈ 23 3/11
The length of CD is about 23 units.
