If m∠ABC is 160°, and m∠ABD is 92°, what is the angle measure of DBC? ∠ABD and ∠DBC are adjacent angles inside ∠ABC.(1 point)
68
80
160
92
Since ∠ABC is 160° and ∠ABD is 92°, the measure of ∠DBC can be found by subtracting the measure of ∠ABD from ∠ABC:
∠DBC = ∠ABC - ∠ABD
∠DBC = 160° - 92°
∠DBC = 68°
Therefore, the angle measure of DBC is 68°.
