Question

If triangle ABC is similar to triangle DEF such that 3AB =DE and BC = 9 ,then EF is equal to

Answer 1

Answer:

3

Step-by-step explanation:

ABC similar to DEF

AB/DE = BC/EF = AC/DF

3/1=9/EF

3XEF=9

EF=9/3

EF=3

Answer 2

Answer:

pls mark as brainliest

Step-by-step explanation:

as both traingles are similar

so

ab/de= bc /ef = ac/ df= 1 ( Thales theorem)

so,

bc/ef= 1

substituting BC value we get

9/ef= 1

9= ef

here is your answer
