Answer:
C
Detailed explanation down below
Step-by-step explanation:
A bisector divides an angle in half, so we can say that:
7x - 27 = x + 57
7x = x + 84
6x = 84
x= 14
So now lets input this information
7 x 14 - 27 = m∠ LMO = 98 - 27 = 71°
14° + 57° = 71°
(Actually we didnt have to do this second equation because both angles should be equal.)
71° + 71° = 142°
So the answer is C : x=14° . m∠LMN = 142°
