text: point a is located 8km south of b and c is located 6km west of a. what is the distance between c and b?   for more explaination:  if a is directly south of b and directly east of c then it would form a right triangle.  you can then use the length of the two legs squared and added together would equal the square of the thrid side.  8*8=64 6*6=36  64+36=100  take the square root and it equals 10
