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.

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°
