Answer:
a = 33 degrees

Thus, a = 90 degrees less 57 degrees = 33 degrees
 
        
             
        
        
        
Answer:
h(x) =  2x²+2
Step-by-step explanation:
Given the function g is defined as follows.
g(x) = 2x²+7
If the graph is translated by 5units vertically downwards, this means that the function will be reduced by 5 units to have;
h(x) =  2x²+7 - 5
h(x) =  2x²+2
 
        
             
        
        
        
I believe you just have to draw 2 little lines in between AB and CD.
        
             
        
        
        
It would be at 35 when you work all then problems together
