Answer:
0.4
Step-by-step explanation:
drawing a triangle with each side correspondent to each of its measurements all you are doing is dividing the side that you would want to find its scale factor of, which in this case you would take AB and DE and have AB/DE dividing that and getting 0.4 as its scale factor.
The answer is B:15
since APWVS ~ HDTFY, PW ~ DT. so you set up a proportion. i hope this explains it clearly for you, if not i'm sorry
