10. Given triangle BCD as shown at right. If GE = 12, GC = 16, and EF = 10, find
DF.
EDF
B

5) Segment B'D' will be parallel to segment BD and will be shorter than segment BD. Please see the attached figure (a) for better understanding.
7) Δ ABC is similar to Δ EDF and x=r*w/z.
8) x+15=28 +12.
9) The line segment which is drawn from point A to point A′ is perpendicular to the y-axis.
13) Its D.Translation of (x, y + 2), reflection over y = 1, and 180° rotation about the origin.

v= 3

Step-by-step explanation:

2-11= -9

-3v/ -9

= 3
