Answer:

b. 23°
c. 157°
d. 23°
e. 157°
f. 23°
g. 157°
Step-by-step explanation:
I know this is the answer I cant put into words why but maybe if you see the answers it will help you to better understand it. A line segment will equal 180°. That's where I got the 157°. You take 180° minus the 23° that they gave you to get 157° for the other corners.
