Answer:
<h2>-28
°</h2>
Step-by-step explanation:
It is given that ∠1 is a right angle that is ∠1 = 90°.
∠8 - ∠1 = ∠ 7 = 62° - 90° = - 28°.
 
        
             
        
        
        
No solution simply because the expression cannot be solved with rational numbers
        
             
        
        
        
The function that is graphed is...
B.) y = |x - 3| - 4 
Since the lines "|" in the function make it a V shape. 
And when you graph the one point where the the 2 lines meet it is.
(-3, -4) 
So this answer is correct. :P
Good Luck! :)
