Carlos and Clarita have been running their Pet Sitters business for quite some time now. Recently, one of the dogs, Fido, got out and ran to the undeveloped area near their house. Unfortunately, Fido fell down into a ditch. Thankfully, he is okay. Carlos and Clarita need to find a wayto get him out. Carlos and Clarita are both 5' 6" tall. They are on opposite sides of the ditch that is 28 feet wide. When Carlos looks at Fido, his line of sight makes a 460 angle below the horizontal. When Clarita looks at Fido, her line of site makes a 380 angle below the horizontal. How deep is the ditch?
