In triangle ABC, the length of side BC is 2 inches and the length of side AC is 10 inches. What is one possible length of side AB, in inches?

given: length+BC=2++.......x
length+AC=10+........r
length+AB=++.........y

using pythagoras theorem

r%5E2=x%5E2%2By%5E2
10%5E2=2%5E2%2By%5E2
y%5E2=100-4
=98
y =sqrt%2898%29
y =sqrt%2849%2A2%29
y =7sqrt%282%29
=AB
