Point o is the center of the given circle. what is the measure of yz?

Step-by-step explanation:

Please refer the diagram I have attached.

Alright, lets get started.

As O is the center, OX and OY will be same because both are radius.

So, the angle OYX will also be 54 degrees.

In triangle OYZ, the angle OYZ  =

As OY and OZ are same because both will be radius.

Angle YZO will also be 36 degree.

the sum of all three angles will be 180, so

Angle YOZ =

Hence the measure of arc YZ will be 108.

Hope it will help :)

4+n=5
