6.
Since the angle is connected to a straight line, it would be equal to 180.
22+x=180 (where the missing angle is x)
Subtract 22 from both sides.
x= 158
7. Those angles are congruent. They would be equal to each other.
84=4x
Divide both sides by 4.
x=21
8. Yes. The angle that is opposite it is congruent and is 50 degrees.
38<50 50 is greater than 38.
I hope this helps!
