The angle measure of DBC can be found by subtracting the measures of ABD and ABC from 180°.
DBC = 180° - ABD - ABC
DBC = 180° - 92° - 160°
DBC = 180° - 252°
DBC = -72°
Since an angle measure cannot be negative, the correct answer is not listed. The angle measure of DBC is not provided in the given information.
