Angle ABC and angle CBD are congruent and adjacent angles. Measure of angle ABD equals 160. Find another measure that is possible for ABC that is not 80.
Thank you!

(360-160)/2 = 100.
It does not say which side of ABD they are measuring.

Sketch angle ABD as 160 degrees. Put C in the exterior, so that BC bisects the 200 degrees that is outside the angle.
So ABC and CBD would each be 100 degrees.
Hoping this helps!
