Answer:
B is your answer: Angle pair "MTS" should be 107 and "STN" should be 73
Explanation:
You need to do 180-73 because "s" is unknown.
That should be 107 degrees.
Angle pair "MTS" should be 107 and "STN" should be 73
This is due to alternate interior angles, same side angles, and congruency properties.
