The first and second weigh 7kg altogether
The second and third weigh 8kg altogether
The first and third weigh 11kg altogether
What is the weight of each cat?

9. Problem 2…
There is a one acre field in the shape of a right angled triangle, with sides of length x and y. At the midpoint of each side there is a post. Tethered to the posts on each side is a sheep. Tethered to the post on the hypotenuse is a dog. The diagram below is not perfect but sort of explains the situation.
Each animal has a rope just long enough to reach the two adjacent vertices of the triangle. How much area outside of the field do the sheep have to themselves?
