Use the following similar triangles (ABC ~ DEF). If AC= 18 when DF=19 and AB=15, what is DE? Solve mathematically. Round your answer to the nearest tenth.

Respuesta :

Answer:

Step-by-step explanation:

As they are similar triangles,we can write

[tex]\frac{AB}{DE}[/tex]=[tex]\frac{AC}{DF}[/tex]

⇒[tex]\frac{15}{DE}[/tex]=[tex]\frac{18}{19}[/tex]

⇒DE=15.8

Answer:

15.8

Step-by-step explanation:DE=15*19/6

DE=15.83=15.8
