The equation x² + y² − 2x + 6y + 3 = 0 is equivalent a. (x − 1)² + (y + 3)² = −3 b. (x − 1)² + (y + 3)² = 7 c. (x + 1)² + (y + 3)² = 7 d. (x + 1)² + (y + 3)² = 10

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?
