Answer: your answer is 195
Step-by-step explanation: 
 
        
             
        
        
        
1+2+3= 6 (even)
2+3+4= 9 (odd)
it can be both
        
             
        
        
        
No it is not base e.  It is 1.015.
An increase of 1.5 % =  1.015  
Year            1,             2,                       3,.........................., 30. 
               30000, 3000(1.015),  30000(1.015)²,........... 30000(1.015)²⁹
Her Total Income is sum over the thirty 30 year period:
Sn =  a(r^n  - 1) / (r - 1);                a = 30000,  r = 1.015,  n = 30
Sn =  30000 ( 1.015^30  -  1) / (1.015 - 1)
      =  30000 (1.56308022 - 1) / (0.015) =  1126160.44
Total =  $ 1 126 160.44
        
             
        
        
        
Answer:
Angle 1 is = 54° ( vertically opposite angles)
Angle 2 is = Angle 1 (corresponding angles are equal)
therefore Angle 2 = 54°
