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

Since ∠ABC is 160° and ∠ABD is 92°, we can find ∠DBC by subtracting ∠ABD from ∠ABC:

∠DBC = ∠ABC - ∠ABD = 160° - 92° = <<160-92=68>>68°.

Therefore, the angle measure of DBC is 68°.
