For the following question:
Peter lives 12 miles west of school and Bill lives north of school.Peter finds the direct distance from his house to Bill is 6 miles shorter than the distance by way of shcool.How many miles north of school does Bil live?
For this after constructing a right triangle I got
-12x = 108 so x=-9 (distance from school to Bill) Does the - in the answer depict anything ?
Edit: My perpendicular was x and my hypotenuse was x-6
