The coordinates below represent a triangle that was dilated.
J(-3,-12) ► J'(-2,-8)
K(-6, -15) → K'(-4,-10)
LC-9, -12) → L'(-6, -8)
What was the scale factor that was used in the
dilation?

i don't know sorry

Step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
