In a right triangle I need to find the length of the missing side.

If..

a = ?

b = 1

c = sqrt(5)

I would know what to do if the square root wasn't there or if it were a perfect square but it's not, please help...

(P.S. if I need to I have to keep it in radical form)

a=2

a^2=c^2-b^2

a^2=(√5)^2 - 1^2

a^2= 5 -1

√a^2 = √4

a=2
