Answer:
scale factor = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
To calculate the scale factor compare the ratio of corresponding sides, image to original.
Comparing the base of both triangles
Figure A = 6 and Figure B = 3
scale factor from A to B is
k = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
