a=2
a^2=c^2-b^2
a^2=(√5)^2 - 1^2
a^2= 5 -1
√a^2 = √4
a=2
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)

Good, you're welcome.
