Answer:
3
Step-by-step explanation:
-(x-4)+5=3x+6-x(BODMAS)
-x+4+5=3x+6-x(collect like terms )
4+5=3x+x-x
9=3x (divide both sides by 3)
9/3=3x/3
3=x

Step-by-step explanation:
The LKM angle is an enclosed angle. So its size is half the arc facing it.
LKM (angle) = ½ LM (arc)
The LMN angle is a shadow angle. So its size is half the size of the arc facing it.
LMN(angle) = ½ LM(arc)
so:
LKM = LMN
