Answer:
125
Step-by-step explanation:
( 3x - 70 ) is exterior angle.
60 and x are interior angles.
Formula : -
Exterior angle of a triangle
= Sum of two interior angles in a triangle
3x - 70 = x + 60
3x - x = 60 + 70
2x = 130
x = 130 / 2
x = 65
m∠LKM = 3x - 70
= 3 ( 65 ) - 70
= 195 - 70
m∠LKM = 125
