Answer:
Angles AXY and YXB are complementary angles because they add up to 90 degrees, which can be inferred by looking at angle BXC.
For this case we must find the value of the following expression:

We have to:

Substituting:

By definition of properties of powers and roots we have:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So:

So we have to:
