Question 924674: a right triangle has hypotenuse c=8 inches and leg b=5 inches find the exact length of the missing side
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! h = sqrt( aa + bb )
8 = sqrt( aa + 5*5 )
8 = sqrt( aa + 25 )
8^2 = (sqrt( aa + 25 ))^2
64 = aa + 25
aa = 64 - 25
aa = 39
a = sqrt( 39 )
a = 6.2449979984
