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
A. 160°
160 degrees
B. 68°
68 degrees
C. 92°
92 degrees
D. 80°
To find the angle measure of DBC, we can subtract the measure of angle ABD from the measure of angle ABC.
m∠ABC - m∠ABD = m∠DBC
160° - 92° = 68°
Therefore, the angle measure of DBC is 68°.
Answer: B. 68°
