In the triangle above, what is the value of b?

(1) c=2 root 2

(2) x = 45

From option 1 it is clear that hypotenuse is 2 root - and one of the side measures as 2. This is clear 45, 45,90 degree traingle
Sufficent

From option 2, it is very much clear, triangle is 45,45,90 degree and hence sufficent

Note - 45,45,90 are in ratio of 1,1,root 2

So Both are sufficient, answer is D
