Joy wants to find the distance, AB, across a creek. She starts at point B and walks along the edge of the river 105ft and marks point C. Then she walks 85ft further and marks point D. She turns 90°and walks until her final location and marks point E. Point E, point A, and point C are collinear.''
1. Can Joy conclude that ABC and EDC are similar? Why or why not?
2. Suppose DE = 90 ft. Calculate the distance of AB to the nearest tenth of a foot. Show your work.
