You can factor out a 3t first, resulting in:

Now, let's factor the equation in the middle using the quadratic equation. Plug in the values to the quadratic equation:

Simplify, you get your 
x's:

To write the equation in simplified form, you just write it this way:
That's your answer ^
 
        
                    
             
        
        
        
The angle would be 70 degrees because 180-110=70
        
                    
             
        
        
        
This is another way of saying what is 165% of 25, because 65% of the sweater is the markup, and you add the markup to the whole sale.
165% is 1.65 in decimal form, so


 is your answer
