<PRE><B>Question 363162</B>
um theres multiple answsers, technically 2 possible answers so you might want to reread the question to find out which side is the hypotnuse. if a= 8 and b=21 then C is greater than 21
if a=8 b=? c=21 so b would be less tha 21

8^2+21^2=c^2
64+441=c^2
505=c^2
22.4722=c

second one could be
8^2+b^2=21^2
64+b^2=441
b^2=377
b=19.4165
