Answer:
A
Step-by-step explanation:
40+6=12
12*X=645
697+645=12500
then,
X=5 and 8
 
        
                    
             
        
        
        
A) the man is 40 and the daughter is 8
b)in 8 years when the man is 48 and the daughter is 16
        
             
        
        
        
Step-by-step explanation:
∑k=150(3k+2) 
First find a1 and a50 :
a1=3(1)+2=5a20=3(50)+2=152
Then find the sum:
Sk=k(a1 + ak)2S50=50(5 + 152)2=3925
 
        
                    
             
        
        
        
Answer:
C) Similar-SAS 
Step-by-step explanation:
 
Here, 
 BSE ~ TES
Now,
 BS = TE (:• being corresponding side )
 BSE = TES (:• Being Corresponding angle
 SE = SE (:•Being corresponding side)
Therefore, 
 the given triangle is similar by 
 SAS axiom
