Answer:
1.  Find < ACB
2. Use that triangles =180 to find <B  = 41
Step-by-step explanation:
1.We need to find < ACB
<ACB +<DBC= 180 They make a straight line
Subtract DBC from each side
<ACB = 180 - <DBC  
We know DCB = 113
ACB = 180 -113
ACB = 67
2.The three angles of a triangle = 180, so we can then find <B
<A +<B + <ACB = 180
72 + B + 67 = 180
Combine like terms
139+ <B = 180
Subtract 139 from each side
<B = 180-139
<B =41
 
                                
             
                    
              
              
                
                
Okay so this is all about interior angles. 
And interior angles all add up to 180. 
Since 113 is an exterior, you need to find the interior of C. 
180-113=67°
Interior of C is 67°
Add 67 and 72. 
now, 180=B+139 
Subtract 139 from 180.
Your answer should be AngleB= 41°
