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 160° 160 degrees 92° 92 degrees 68° 68 degrees 80°
Since ∠ABC is 160° and ∠ABD is 92°, we can find the measure of ∠DBC by subtracting the measure of ∠ABD from ∠ABC.
∠DBC = ∠ABC - ∠ABD
∠DBC = 160° - 92°
∠DBC = 68°
Therefore, the angle measure of DBC is 68°.
