Question

1. Kayla wants to find the width, AB, of a river. She walks along the edge of the river 100 ft and marks point C. Then she walks 22 ft further and marks point D. She turns 90° 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? (Be sure to state a triangle similarity postulate) (b) Suppose DE = 32 ft. What can Kayla conclude about the width of the river? Explain.

Answer 1

You are given Kayla's walking distance along the edge of the river 100 ft and marks point C, then she walks 100 ft further and marks point D and she turns 90° and walks until her location, point A, and point C are collinear. She marks point E at this location. ABC and EDC are congruent. thats just what i think it is tho
