Answer:

The measure of angle ABD is [tex]40\°[/tex]

Step-by-step explanation:

we know that

[tex]m<CBD+m<ABD=180\°[/tex] -----> by supplementary angles

see the attached figure to better understand the problem

we have

[tex]m<CBD=140\°[/tex]

substitute and solve for the angle ABD

[tex]140\°+m<ABD=180\°[/tex]

[tex]m<ABD=180\°-140\°=40\°[/tex]
