slope = 5
Step-by-step explanation:

 
        
             
        
        
        
If they do not have solutions (intersections).
If they do not have intersections then they must be parallel. Imagine it on the graph
        
             
        
        
        
I’d say 21 and -1 :)
21 * -1 = -21
21 - 1 = 20
        
                    
             
        
        
        
In mathematics, a rational number is a number such as −3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q
        
             
        
        
        
Answer:
 and
  and  
Step-by-step explanation:
The ratios of sine and cos are defined as follows:
 , and
 , and

The hypotenuse is always the side opposite of the 90 degree angle (for the given triangle, the hypotenuse is 85)
Since we are looking at the angle A, the opposite side with respect to A would be the side length of 84. That leaves the side 13 as the adjacent side.
Thus, we can now write:


The correct answer is  the first answer choice.
