Assuming annual compounding, then:
 FV=15000*(1+.035)^15
 FV=15000*1.6753488307521611831782355996538
 FV=$25130.23
 At the end of 15 years, Tom should have $25130.23 in his account.

You are working with the Cosine of the angle.
Hypotenuse = 12.5
Base = 3
Theta = ?
Solution
Cos(theta) = base / hypotenuse         Substitute values
Cos(theta) = 3 / 12.5                            Divide   
Cos(theta) = 0.24                                  Tale the inverse cos
theta = cos-1(0.24)
theta = 76.11 degrees
 
        
                    
             
        
        
        
You could make them have the same denominator, making it 7/10-5/10=2/10. 
The answer is 2/10, or simplified, 1/5.
