I'm really bad at math and since we're in quarantine, I can't exactly go to my teacher for help. Hopefully someone here can explain to me what the problem is (what it's asking me) and how I can find the new coordinates. Thank you and have a good day!

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 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 δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?
