Answer:
The answer is 4 
Step-by-step explanation:
x^2-2x-8=1/4x-1
x^2-9x/4-7=0
4x^2-9x=28
Therefore if we take value of x as 4 aur eq.get balanced...
 
        
             
        
        
        
Answer:
   D.  14°
Step-by-step explanation:
The Law of Sines tells you sides are in proportion to the sine of the opposite angle:
   sin(A)/BC = sin(B)/AC
   sin(A) = BC/AC·sin(B)
   A = arcsin(BC/AC·sin(B)) = arcsin(7/28·sin(75°)) ≈ 13.974° ≈ 14°
