Question

Triangles ABC and DEC are similar. How far is it from point A to point D?

Answer 1

40 feet

Explanation:

We need to find the scale factor. Two corresponding sides are AB and ED.

Let s = scale factor

20x = 12 Divide both sides by 20

x = .6

To find CD take the corresponding side 25 and multiply it by the scale factor of .6

25 x .6 = 15

Side CD is 15

CD + AC = AD

25 + 15 = 40
