Answer:  A) 46</h3>
Explanation:
The angles shown are same side interior angles.
For line L to be parallel to line M, the same side interior angles must be supplementary, or they must add to 180.
28+(3x+14) = 180
28+3x+14 = 180
3x+42 = 180
3x = 180-42
3x = 138
x = 138/3
x = 46
 
        
        
        
You go down to the negative number x is first and then you go to the positive number which is y
        
             
        
        
        
Given that a pair of shoes has a price of $62, and it is discounted for 20%, so this would mean that $12.4 is discounted to the original price. So the new price would be $49.6. And now, since there is a 5% tax added, $2.48 is added so the new total price would be $52.08. The answer would be option D. Hope this helps.
