<u>Answer:</u>
∠DBC = 40°
<u>Step-by-step explanation:</u>
We are given a figure where we know that the angle m∠1 = 65°, m∠2 = 60° and m∠6 = 85°. With the help of these given measures of the angles, we are to find the measure of the angle m∠DBC.
Since the sum of angles in a triangle is equal to 180 degrees, so:
∠1 + ∠2 + ∠3 = 180
∠3 = 180 - (65 + 60)
∠3 = 55°
Also ∠6 and ∠B are alternate interior angles so if ∠6 = 85° then ∠B is also = 85°.
Now that we know ∠3 and ∠B, we can find ∠DBC:
∠DBC = 180 - (85 + 55)
∠DBC = 40°

Answer:
If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
