Answer: There is 680% increase for the fund. 
Step-by-step explanation:
Since we have given that 
Number of shares they purchased = 1000
Cost of per share at the time of their marriage = $10 
So, Amount of fund will be 

Cost per share after 30 years = $78
So, Amount of fund will be 

Percentage of increase for the fund will be given as 

Hence, there is 680% increase for the fund. 
 
        
                    
             
        
        
        
1. The angles DCA and BCA are the same. 
2. Angles DCA and BCA are not supplementary. Since the both of them add up to 90° (we know that angle c is equal to 90° because in a right square all angles are 90°) the angles would be complementary, not supplementary. Supplementary angles add up to 180°
 
        
             
        
        
        
∠LKH corresponds to ∠FGK, as it is the angle on the line that crosses the parallel lines (an F angle).
Therefore, ∠LKH=25°
