Question

Triangle ABC ~ triangle DEF and the similarity ratio of triangle ABC to triangle DEF is 43 . If AB = 60, what is DE?

Answer 1

It is given in the question that , Triangle ABC ~ triangle DEF , and the similarity ratio is

`= (4)/(3)`

Let DE = x

, And we will get

`image`

Therefore the length of DE is 45.

Answer 2

Since the similarity ratio is 43, then:

`AB=43* DE\\\text{ then:}\\ DE=(AB)/(43)=(60)/(43)`
