A.35
B.25
C.50
D. The distance cannot be determined

A. 25

Step-by-step explanation:

1- See the length of XA

2- Divide length by 2

3- 50 divided by 2 equals 25

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
