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.
