Answer:

  C.  72°

Step-by-step explanation:

The measure of angle VYX is half the sum of the marked arcs:

  ∠VYX = (64° +152°)/2 = 216°/2 = 108°

Angle XYZ is the supplement of this:

  ∠XYZ = 180° -108°

  ∠XYZ = 72°

The measure of the angle XYZ will be [tex]72^0[/tex] .

What is angle ?

Angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

We have,

Arc [tex]XYV = 64^0[/tex]

Arc [tex]ZYW = 152^0[/tex]

Now,

We know that the measure of the arc is same as that of central angle..

So from the above mentioned statement,

We get,

[tex]\angle XYV =64^0[/tex] and,

[tex]\angle ZYW =152^0[/tex]

From the given figure it can be assumed that,

[tex]\angle VYW=\angle XYZ[/tex]

Because they are vertically opposite angles.

So,

Let [tex]\angle VYW=\angle XYZ=x[/tex]

And,

Sum of all angles of circle is equals to [tex]360^0[/tex] .

i.e. [tex]\angle VYW+ \angle XYZ + \angle XYV + \angle ZYW =360^0[/tex]

⇒[tex]x+x+64+152=360[/tex]

[tex]2x=360-216[/tex]

[tex]2x=144[/tex]

[tex]x=72^0[/tex]

So, measure of angle XYZ is [tex]72^0[/tex] .

Hence, we can say that the measure of the angle XYZ will be [tex]72^0[/tex] .
