Question

BD is the angle bisector of ZABC.

If m ABD=25° find m/DBC.

A:50°

B:25°

C:750

D:100°

Answer 1

B:25°

Explanation:

Now
`\angle ABC` gets bisected by
`BD`.

`\angle ABD=25^(\circ)`

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
`25^(\circ)` so the other angle has to be
`25^(\circ)` also.

Hence, the
`m\angle DBC=25^(\circ)`.
