Answer: ∠JKM =
and
∠JKM = 
Step-by-step explanation:
Since we have given that
∠JKM=10y+6
∠MKL=8y-6
Since they are linear pairs ,
So, 
∠JKM = 
and
∠MKL = 
You can fill the choices into the equations for x and solve then to see if they are correct. For example, you could put -3 and 3/2 into x^2-12x+27=0
Which would make (-3)^2-12(3/2)+27=0.
From the picture I posted, you can see that 0=0, so the equation is correct
