♥! 20 point & brainliest to the best answer! ♥

stacey wants to find the width, de, of a river. she walks along the edge of the river 22 ft and marks point c. then she walks 100 ft further and marks point b. she turns 90° and walks until her location, point e, and point c, are co-linear. she marks point a at this location, as shown.

1. can stacey conclude that ∆abc and ∆edc are similar? why or why not?
suppose de = 35 ft. what can kayla conclude about the width of the river? explain.

By the given diagram,

The sides of the triangles ABC and EDC are,

BC = 100 feet, DC = 22 feet and DE = 35 feet(given)

  ( Right angles )

   ( Vertically opposite angles )

( By AA similarity postulate )

Thus, she correctly concluded that triangles ABC and EDC are similar.

Since, the corresponding sides of similar triangles are always in same proportion.

⇒  

⇒  

⇒  

By substituting the values,

⇒  

⇒  

Hence, she concluded that the width of the river is approximately 159.09 feet.

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.
