Y=64
79+37=116
180-116=64
all angles of a triangle adds up to 180
add the two given angles and subtract that from 180 to find the missing angle
        
             
        
        
        
Answer:
The nearest whole yard would be 1 or 1.0 because 8 is larger than 5 so you would round up giving you 1 
 
        
             
        
        
        
Answer:

 does not exist
 does not exist
Step-by-step explanation:
Inserting 2 to both formulas, you get different results. In that cases, a limit does not exist
 
        
             
        
        
        
Opposite interior angles are equal, so 
4x - 10 = 2x + 20
2x - 10 = 20
2x = 30
x = 15
 
        
                    
             
        
        
        
The exact answer is 123.592105263
