1) x= 2
6x2+10=22
2) x = 2
6x2-4=4x2
        
             
        
        
        
Answer:
20
Step-by-step explanation:
 
        
             
        
        
        
JK = MN because of Given
∠JLK = ∠MLN because of the vertical angle theorem
JL = LN because of definition of midpoint
ΔJLK = MLN because of SAS
∠K = ∠N because corresponding angles of congruent triangles are congruent.
Hope this helps!<span />
