Answer:
 It has no special appearance. 
Step-by-step explanation:
Any angle of measure 180° or less is supplementary to some angle. A supplementary angle is one that is the difference between 180° and the angle you have. That is, two supplementary angles total 180°.
__
Supplementary angles are readily identifiable in a number of geometries. Adjacent angles of a parallelogram are supplementary; linear angles are supplementary. Same-side interior angles where a transversal crosses parallel lines are supplementary.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
(f+g)(x) = f(x) + g(x) = 3x-1 +x²-6 
(f+g)(x) = x² +3x -5 .....( answer : B )
 
        
             
        
        
        
Step-by-step explanation:
-4x + 3 < 23 
-4x < 20 
x > -5 
hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating. 
we can just keep the question as it is and calculate.
