I have been working on this problem for a while and for some reason I don't come up with the answer.

a^2+b^2=c^2

I came up with 2square root 5 please tell me if this is correct.

In a right triangle, Find the length of the side not given b=1, c=square root 10

thank you.

a^2 + b^2 = c^2

a^2 + (1*1) = 10

a^2 = 9

Can you take it from there?
