Jill and sonja lived in different towns and decided it would be fun to get a homing pigeon to send messages to each other. (a homing pigeon will fly to a specific place, its home, and a small message can be attached to its leg.) to drive from jill's house to sonja's, you need to go 3 miles east and 4 miles south. if the pigeon flies directly from one house to the other, how far does the pigeon fly to deliver the message?

7 miles
25 miles
5 miles
12.5 miles
