Converse (switch p and q)
If an angle is obtuse, then it measures 128°
This is false (a 127° angle is obtuse, but it does not measure 128°)
_____________________________________________________________
Inverse (negations of p and q)
If an angle does not measure 128°, then it is not obtuse
This is false (a 127° angle does not measure 128°, but it is obtuse)
_____________________________________________________________
Contrapositive (negations of p and q, then switch their places)
If an angle is not obtuse, it does not measure 128°
This is true (any 128° is obtuse; no exceptions)
        
             
        
        
        
Answer:
Explanation:
19.
P = 2(x - 3 + 7x + 1)
= 2(8x - 2) 
= 16x - 4
20. 
P = 3y + 5 + y - 4 + 6y
= 10y + 1
