Answer:
B:25°
Step-by-step explanation:
Now [tex]\angle ABC[/tex] gets bisected by [tex]BD[/tex].
[tex]\angle ABD=25^{\circ}[/tex]
Since, the angle is bisected, this means that the angle is split into two equal parts or the angle is halved.
We know that one of the angles is [tex]25^{\circ}[/tex] so the other angle has to be [tex]25^{\circ}[/tex] also.
Hence, the [tex]m\angle DBC=25^{\circ}[/tex].
