I'm guessing d b are equal and a and c are equal or I don't think we would be able to solve so going on that 
if angle d is 57 angle b must also be 57 
A parallelegram has angles that add up to 360 
So 360= 57+57+2c 
Solve 
360=114+2c
-114 both sides 
246=2c 
÷2 both sides 
123=c
        
             
        
        
        
Answer:
no solution
Step-by-step explanation:
y = x+1 and y = x + 2 don't touch because they are parallel
if you don't know what parallel means, just search it up, but i can explain it to you:
parallel means same slope or same steepness of line
