Freind it's answer is B.25
Step-by-step explanation:
First you have to prove that the triangle XYZ and AYZ are congruent.
There we have YZ in common...
Angles XYZ and AYZ are given congruent...
Also angles XZY and AZY are given 90 degrees.....
Hence, Triangle XYZ is congruent to triangle AYZ....
So,XZ=AZ(Congruent Parts of Congruent Triangle)
Now,we have XZ+AZ=XA
So,XZ+AZ=50cm
=2XZ=50 or 2AZ=50
Hence,AZ=25cm
