1)y = 1/2x+4
y = -2x-1
2)y-x=-7
y=-3x + 1
3)y = x
y = 2x – 1 write your answer in coordinates

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?

Given: ab ≅ bc and ao ≅ oc ok − angle bisector of ∠boc find: m∠aok
