Please help, and show work if you can :))

Answer 1

C

Detailed explanation down below

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°
