To find the angle Q we can us the sin law so:

So we can solve for Q so:
 
 
        
             
        
        
        
$220.87 , (it would be $220.88 if you have to round up though
 
        
             
        
        
        
All you do is use the a+b=c formula lets plug it in
15+b=35
15+20=35
35=35
The answer is 20
        
             
        
        
        
I believe that it's A neither, because I don't think that it could be displayed on a coordinate graph when it has an exponent in it. So I think it's A. Let me know if I'm correct. ;-)
