PLEASE HURRY!!

Side A B is parallel to Side D E in the map below.

Triangle A B C. Side A B is 15 feet and side B C is 9 feet. Triangle C D E. Side C D is 6 feet and side D E is x feet.

Which proportion solves for the distance between D and E?
StartFraction 9 Over 6 EndFraction = StartFraction x Over 15 EndFraction
StartFraction 6 Over x EndFraction = StartFraction 15 Over 9 EndFraction
StartFraction 9 Over 6 EndFraction = StartFraction 15 Over x EndFraction
StartFraction 6 Over 15 EndFraction = StartFraction 9 Over x EndFraction

Let's apply BPT theorem(Not necessary we can apply common ratios and similarities)

  • AB/BC=CE/DE

Put values

  • 15/9=6/x

Option B

Let's solve it out

  • 15x=54
  • x=54)15
  • x=18/5
  • x=3.6
