Answer:
DAB + EBA = 180°, CA and CB are bisectors of the DAB and EBA respectively. So, the bisectors of the two adjacent supplementary angles include a right angle.
Hence PROVED!

Step-by-step explanation:
Let the adjacent angles be x&y.
Given x+y=180°
When bisector are drawn, the angle between the bisector is:
x/2+y/2=x+y/2=180/2=90°
