For this case we must indicate the cosine of A, of the figure shown. By definition:
[tex]Cosine (A) = \frac {Cateto\ adjacent\ to\ the \ angle} {hypotenuse}[/tex]
Substituting the values we have:
[tex]Cosine (A) = \frac {48} {73}[/tex]
So, we have to:
[tex]Cosine (A) = \frac {48} {73}[/tex]
Answer:
Option D
