Triangle XYZ is a dilation of triangle ABC with a scale factor of 2. This means that the side lengths of Tri ABC were all multiplied by 2 to get Tri XYZ. So to find the length of Line XZ, we would just multiply the length of Line AC by 2.

3 * 2= 6

The answer to your question is C. 6 units

Set each sides of a triangle as a fraction, and set both triangles equal to each other.


Let side XZ's measurement = x


Set the sides as fractions equal to each other.


3/4 = x/8


Cross multiply


3/4(4)(8) = x/8(8)(4)


3(8) = x(4)


Simplify


24 = 4x


Isolate the x. Divide 4 from both sides


24/4 = 4x/4


x = 24/4


x = 6

(C) 6 units is your answer


hope this helps
