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) Responses 80° 80 degrees 68° 68 degrees 92° 92 degrees 160°
Since ∠ABC is 160° and ∠ABD is 92°, we know that ∠DBC must be the difference between these two angles.
∠DBC = ∠ABC - ∠ABD
∠DBC = 160° - 92°
∠DBC = 68°
Therefore, the angle measure of DBC is 68°.
