Atriangular space between three streets has measurements shown. how much new curbing will be needed to go around the space? how much sod will be needed to cover the space? a right triangle has a vertical side of length 42 meters, a horizontal side of length 34 meters, and a third side of length 54.0 meters. 42 m 54.0 m 34 m the space needs 130.0 m curbing. the space needs 714 m squared sod.

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?
