Answer:
hi
Step-by-step explanation:
thx for the points. you so kind
 
        
                    
             
        
        
        
<span>The answer is B. 
The reason being is that in this option they have set both sides of the equation separately equal to y. Since they are equal to each other, they would both have to be equal to an unknown y. This would look like this. 
y = 1/4x - 3
y = 1/2x + 8. 
Then to remove the fractions in each, they multiplied by the denominator associated with x. So, you multiply the first equation by 4. 
4y = x - 12. 
Then they solve for the numerical value at the end. 
4y - x = -12. 
You can do the same with the second equation. 
y = 1/2x + 8
2y = x + 16
2y - x = 16
These are now the two equations above. </span>
        
             
        
        
        
Alright here we go
First we need to find the upper angle by doing 180 - 143 = 37. Because it’s a straight line.
Second we need to find angle ADC
a triangle has 180 degrees, and we have 38 and 37.
180 - (38+37) = 105
then we find what the question wants: 
180 - 105 = 75 degrees
