Answer:

16 degrees

Step-by-step explanation:

The question is

Find the measure of angle R

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

so

In this problem

[tex]m\angle N+m\angle R=109^o[/tex]

we have

[tex]m\angle N=93^o[/tex]

substitute

[tex]93^o+m\angle R=109^o[/tex]

[tex]m\angle R=109^o-93^o=16^o[/tex]
