They must be complementary. these 2 angles MUST equal 90 degrees because there is a right angle that is 90 degrees in the triangle already and all triangles have an angle sum of 180 degrees. the answer is complementary
        
             
        
        
        
As both 4/2 and 5/2 are rational Numbers and Sum of rationals is a Rational Number.
Therefore, 9/2 is a Rational Number.
        
                    
             
        
        
        
Answer:
I think it is a maximum value.
 
        
             
        
        
        
Answer:
Simplest polynomial: x²+x-12
Step-by-step explanation:
zeroes of polynomial= 3,-4
Therefore,
f(3) =0
f(-4)=0.
By factor Theorem 
(x-3) and (x+4) are factors
so simplest polynomial is 
(x-3)(x+4)
= x² - 3x + 4x -12
= x² + x -12
.
Hope it helps
 
        
             
        
        
        
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values.
