Answer:
Step-by-step explanation:
Sum of interior angles of a triangle = Exterior angle
m∠VWX + m∠WVX = Exterior angle = 155°
m∠VWX + 86° = 155°
m∠VWX = 69°
 
        
                    
             
        
        
        
Answer:
Reliability 
Step-by-step explanation:
Here, we want to select the option that best completes the given question
The correct answer is the reliability 
When we speak of how reliable a type of measurement is, we are simply referring to how free the particular measurement is from random error
Measurements that are free from random error are said to be reliable 
 
        
             
        
        
        
The slide costs $2 each time you ride. $15/2 = 7.5 so you can ride it 7 times.
        
                    
             
        
        
        
12.8$, you would divide 2.40 by 3 to get the cost per ounce. Then multiply that by 16 to get the cost for one pound.
        
             
        
        
        
Multiply the one by the 2 and the three by the 2. Put the decimal back in and add the negative sign
