a^2+b^2=c^2
where c is the bigger of the 3 numbers

anonymous · Answer

ohh okay I can do that

myininaya · Answer

so have you decided which of the 4 sets above satisfy a^2+b^2=c^2?

myininaya · Answer

which of the following are true:
$$5^2+12^2=13^2\
12^2+13^2=15^2\
10^2+12^2=14^2\
10^2+12^2=22^2$$
