Question 25679: How do you find the unknown lenght of a leg given the lenghts of the hypotenuse and the other leg? Answer by elima(1433) (Show Source):
You can put this solution on YOUR website! By using the pythagorean theorem; +=
Where a & b are legs and c is the hypotenuse, is all you do is plug in the given amounts and then solve for the unknown.
ex;
a=9
b=?
c=15 +b=
81+b=225
b=225-81
b=144 =12
So b=12
Hope you understand
