Answer

$m\widehat{DB}=90^{\circ}$

Work Step by Step

We must know that the measure of a minor arc is equal to the measure of its corresponding central angle. In the given question, we can see that the corresponding angle of minor $\widehat{DB}$ is $\angle DPB$ . We have: $m \angle DPB=90^{\circ}$, so or, $m\widehat{DB}=90^{\circ}$
