Question

( Angle congruence and transformation ) Plz, if anyone can answer these I would appreciate it so much​

Answer 1

see explanation

Explanation:

Since the triangles are similar then the ratio of corresponding sides are equal

(a)

`(AB)/(DE)` =
`(BC)/(EF)` , substitute values

`(AB)/(17.64)` =
`(6.3)/(13.23)` ( cross- multiply )

13.23AB = 111.132 ( divide both sides by 13.23 )

AB = 8.4

(b)

`(DF)/(AC)` =
`(EF)/(BC)`, substitute values

`(DF)/(4.1)` =
`(13.23)/(6.3)` ( cross- multiply )

6.3DF = 54.243 ( divide both sides by 6.3 )

DF = 8.61
