Answer:

Therefore the measure of the angle z is

[tex]m\angle z= 122\°[/tex]

Step-by-step explanation:

Consider a Triangle XYZ having angles,

∠x = 31°  

∠y = 27°

To Find:

m∠z =?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

[tex]\angle x+\angle y+\angle z=180\°[/tex]  ..Triangle sum property.

Substituting the values we get

[tex]31+27+\angle z=180\\\angle z=180-58=122\\\angle z=122\°[/tex]

Therefore the measure of the angle z is

m∠z=122°
