B = 16

Right angled Isoc, triangle sides are in the ratio x:x: sqrt(2)x

So, x+x+sqrt(2)x = 16 + 16*sqrt(2)

x = (16+16*sqrt(2))/ (2+sqrt(2))

We need to find out sqrt(2)*x and when you solve the above equation, it comes out as 16

$$2x+sqrt(2)x = 16+16 *sqrt(2)$$

$$sqrt(2)*x(1+sqrt(2)) = 16(1+*sqrt(2))$$

$$sqrt(2)*x=16$$
