Question

Triangle M R N. Angle N is 98 degrees. Side N M extends to form exterior angle with a measure of 109 degrees.
16 degrees
19 degrees
71 degrees
87 degrees

Answer 1

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

$m\angle N+m\angle R=109^o$

we have

$m\angle N=93^o$

substitute

$93^o+m\angle R=109^o$

$m\angle R=109^o-93^o=16^o$

Answer 2

Answer: 16 degrees

Step-by-step explanation: 109-93 is 16
