To measure the distance (DC) across a pond, a surveyor takes points A and B so that AB is parallel to DC. If AB = 60 feet, EB = 48 feel, and ED = 80 feet, find DC.
Hello, symmetry!
You forgot to tell us where point is, but I have a good guess.To measure the distance across a pond,
a surveyor takes points and so that .
If , find .Code:D * - - - - - - - - - - - - - - - * C * * 80 * * * * *E * * 48 * * A * - - - - - - - - - - - * B 60
From the similar triangles, we have: .
Therefore: .
