Question

if db is a bisector, what is the measure of angle dbc? *

Explanation:

Step1: Recall the definition of an angle bisector

An angle bisector divides an angle into two equal parts.

Step2: Calculate the measure of angle \(DBC\)

Since \(DB\) is an angle bisector, \(\angle ABD=\angle DBC\). Given \(\angle ABD = 65^{\circ}\), so \(\angle DBC=65^{\circ}\)

Answer:

\(65^{\circ}\) (the first option)
