Answer:

The direct distance between the birds is 12.64 miles.  

Step-by-step explanation:

We have, one bird flew 12  miles west and another  bird flew 4 miles north.  It is required to find the direct distance  between the birds. It means we need to find the resultant of two displacement. It can be given by :

$d=\sqrt{12^2+4^2} \\\\d=12.64\ \text{miles}$

So, the direct distance between the birds is 12.64 miles.
