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 92° 92 degrees 160° 160 degrees 80° 80 degrees 68°
The sum of the angle measures in triangle ABC is 180 degrees.
So, m∠DBC = 180 - m∠ABC - m∠ABD = 180 - 160 - 92 = 80 degrees.
Therefore, the angle measure of DBC is 80°.
