You can put this solution on YOUR website!
The right angle triangle formula is A%5E2%2BB%5E2=C%5E2
because c= hypotenuse
and you have a side a/b
you can isolate the other side by making the equation A%5E2=C%5E2-B%5E2
by quaring the information you have you can fill in the equation
A%5E2=sqrt%2858%29%5E2-7%5E2
and by square routing the answer you find a
A=3
so your third side is equal to 3
