Kayla wants to find the width, AB, of a river. She walks along the edge of the river 100ft and marks point C. Then she walks 22ft further and marks point D. She turns 90 degrees and walks until her location, point A, and point C are collinear. She marks point E at this location, as shown.(A) Can Kayla conclude that triangle ABC and triangle EDC are similar? Why or why not? (B) Suppose DE = 32ft. What can Kayla conclude about the width of the river? Explain.Please help? Question solved general 5 months ago 2378
