Answer:
Step-by-step explanation:
 x  = 52° + 90° ( exterior angle of a triangle is equal to the sum of two opposite interior angles )
x = 142°
 
        
             
        
        
        
18+36=54 
i tried to do all of these and none of them add up to 54
        
                    
             
        
        
        
Answer:
Mary is correct we don’t know the temperature but it can be implied that one is 20 and the other is -20 because of absolute value which is the distance a number away from zero that means that you have two answers or two days in this case that both have an absolute value of 20

Answer:
d) The limit does not exist
General Formulas and Concepts:
<u>Calculus</u>
Limits
- Right-Side Limit:                                                                                              
- Left-Side Limit:                                                                                                
Limit Rule [Variable Direct Substitution]:                                                             
Limit Property [Addition/Subtraction]:                                                                   ![\displaystyle \lim_{x \to c} [f(x) \pm g(x)] =  \lim_{x \to c} f(x) \pm \lim_{x \to c} g(x)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clim_%7Bx%20%5Cto%20c%7D%20%5Bf%28x%29%20%5Cpm%20g%28x%29%5D%20%3D%20%20%5Clim_%7Bx%20%5Cto%20c%7D%20f%28x%29%20%5Cpm%20%5Clim_%7Bx%20%5Cto%20c%7D%20g%28x%29)
Step-by-step explanation:
*Note:
In order for a limit to exist, the right-side and left-side limits must equal each other.
<u>Step 1: Define</u>
<em>Identify</em>

<u>Step 2: Find Right-Side Limit</u>
- Substitute in function [Limit]:                                                                          
- Evaluate limit [Limit Rule - Variable Direct Substitution]:                            
<u>Step 3: Find Left-Side Limit</u>
- Substitute in function [Limit]:                                                                          
- Evaluate limit [Limit Rule - Variable Direct Substitution]:                            
∴ Since   , then
