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]
Answer: 16 degrees
Step-by-step explanation: 109-93 is 16
