Answer:
a° = 41°
b° = 139°

Step-by-step explanation:
Vertical angles are opposite angles created by a pair of intersecting lines, and are equal in measure.
Angle a° is a vertical angle with the angle created by D and B.
a° = ∠DB
a° = 41°

Straight lines are 180°.
Line DC is straight and is divided into two angles, which will add to 180°.
b° + 41° = 180°
b° = 180° - 41°
b° = 139°
