Answer:
The Qn aint correct 
it would make more sense if the figures invested where different
8% of 19k + 9% of 19k =1620 
the figures are the same so even if we shifted the first 19k to the second side of 9% still it could make no sense(remain the same)
 
        
             
        
        
        
It’s D, y = 4.

Answer:
d. 540 deg
Step-by-step explanation:
2 pi radians = 360 deg
(360 deg)/(2pi rad) = 1
3 pi * (360 deg)/(2 pi rad) = 3 * 180 deg = 540 deg
 
        
             
        
        
        
Answer:
SAS
Step-by-step explanation:
Given: Two triangles ΔABD and ΔDCA,  
We have, AD=AD (normal)  
∠A=∠A (Given)  
BA=CD (Sides inverse to rise to points are consistently equivalent)  
With the SAS rule of congruency,  
ΔABD≅ΔDCA
