The diagram below shows triangle MNR with ray NM.
What is the measure of MRN?


115 is the measure of the exterior angle.  That means that angle RMN is 180-115.  That gives us that angle RMN = 65.  By the Triangle Angle-Sum Theorem, all the angles in a triangle add up to 180.  So angle MRN is 180-65-97 which is 18.  18° is your answer.
