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, Can You Find DC.?

Let x = DC.
Since ∆ABE is similar to ∆CED. The lengths of their corresponding sides are in proportion.

X / 60 = 80 / 48
48x = 80(60) = 4800
x = 4800 / 48= 100 ft.
