Ok so let me help you with this. Here is the procedure:
 <span>r² = x² + y² = 8² + 6² = 100 
r = 10 
x = r cosθ 
y = r sinθ 
sinθ = y/r = 6/10 = 3/5
</span>Hope this is what you are looking for
        
                    
             
        
        
        
Answer:
The number of baseball card to begin with is 143
Step-by-step explanation:
Let The number of baseball cards = x 
The number of sold baseball card = 60% of x
                                                          = 0.6 x 
The number of left baseball card = x - 0.6 x = 0.4 x 
The number of card gave away = 30 % of left cards 
                                                      = 0.3 × 0.4 x = 0.12 x 
The number of card left in his possession = 40 
So, 0.6 x + 0.12 x + 40 = x 
Or,  40 = x - 0.6 x - 0.12 x 
Or,  40 = 0.28 x
∴   x =  =  142.85 ≈ 143
  =  142.85 ≈ 143
Hence The number of baseball card to begin with is 143  Answer
