Answer:
mine ended june 9th but i got summer school for 2 classes lol
 
        
                    
             
        
        
        
We know that the perimeter of a rectangle is twice the length, plus twice the width.  
P = 2L + 2W  
We also know that the perimeter is 156.  
P = 156  
Finally, we know that the width is 12 less than the length.  
W = L - 12.  
The next thing that we do is substitute the information that we have into the original equation:  
P = 2L + 2W  
156 = 2L + 2(L - 12)  
From this point we start to solve  
156 = 2L + 2L - 24 <---we multiplied the '2' through the parenthesis  
156 + 24 = 2L + 2L - 24 + 24  
180 = 2L + 2L <--- getting like terms on same sides  
180 = 4L <---combining like terms  
180/4 = 4L/4 <--- getting like terms on same sides  
45 = L <---now we have a value for L  
Now we take the known value for L and substitute it in to our equation for W  
W = L - 12  
W = 45 - 12  
W = 33  
So now we have Length = 45 and Width = 33.

We need to find the value of the hypotenuse in order to solve this problem.
12^2+4^2=H^2
Therefore:
H=√(144+16)
H=4√10
Now:
sin(G)=O/H=4/(4√10)
=1/(√10)
=(√10)/10
