Answer:
   x = 5.4
Step-by-step explanation:
The segment sum theorem tells you ...
   AB +BC = AC
   36 +(5x -9) = 54
   5x = 27 . . . . . . . . . . . subtract 27 from both sides
   x = 5.4 . . . . . . . . . . divide by 5
 
        
             
        
        
        
Sin(Angle) = Opposite Leg /  Hypotenuse
Sin (Angle B) = 2 / 3
Angle B = Arcsin(2/3)
Angle B = 41.81 degrees.
