19. 60* - a straight line is 180* - the other side which is 120* (supplementary)
20. 132* - the angle below is the same as the other side of this angle, 180* - 48* (same side interior angles) 
21. 48* - these are the same angle just in different placements (corresponding angles)
22. 70* - same angles just different placement (alternate interior angles)
23. 85* - these are vertical angles so they’re the same
24. 114* - same angle just different placement (alternate exterior angles)

Answer:
A. 
Step-by-step explanation:
So we are given the function: 

To find the inverse of the function, we simply need to flip <em>f(x)</em> and <em>x</em> and then solve for <em>f(x)</em>. Thus: 

So the answer is A. 
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
y + 3 = -3(x + 8)
y  + 3 = -3x - 24
y = -3x - 27
