Answer:
B) 0.85
Step-by-step explanation:
By definition, complementary angles add to 90 degrees. 
The given angle 58 degrees is complementary to 90-58 = 32 degrees. The two angles 58 and 32 add to 90.
Therefore, cos(32) = 0.848 = 0.85
 
        
                    
             
        
        
        
Assume he played x games in total.
So x * 60% = 12
->x = 12 / 60% = 20
        
                    
             
        
        
        
     The Definition of Porcentage is given by:
 
      Where Vx is discounted value or increased, and Vt is total value. The discount decreases the "p" value.
