Explanation:

We would be applying similar triangles theorem.

If you check the image, there is a small triangle and a big triangle

For similar triangles, the ratio of the corresponding sides are equal.

Trianglke AEB is similar to triangle ECB

AD corresponds to AB

ED corresponds to CB

AD/AB = ED/CB

AD = 8 ft,

AB = AD + DB = 8+24 = 32

ED = 5 ft

CB = ?
