Someone can help me pleaseeee, for tonight with 2 or 3 will be fine
FIND THE LENGTH

Answer 1

4)..21 units

5). 15 units

6). 25 units

Explanation:

4). Since ΔABC ~ ΔDEF,

Their corresponding sides will be proportional.

`(AB)/(DE)= (BC)/(EF)= (AC)/(DF)`

Since,
`(AB)/(DE)=(AC)/(DF)`

`(14)/(42)=(7)/(x)`

x =
`(42* 7)/(14)`

x = 21 units

5). Since ΔABC ~ ΔDEF,

`(AB)/(DE)=(BC)/(EF)=(AC)/(DF)`

`(AB)/(DE)=(BC)/(EF)`

`(6)/(9)=(10)/(x)`

x = 15 units

6). Since ΔABC ~ ΔDEF,

`(AB)/(DE)=(BC)/(EF)=(AC)/(DF)`

`(BC)/(EF)=(AC)/(DF)`

`(6)/(30)=(5)/(x)`

x = 25 units
