Answer:
m∠1 = 92°
Step-by-step explanation:
∠2 corresponds to the supplement of ∠3 if (and only if) lines a and b are parallel. We find that
m∠2 + m∠3 = 73° +107° = 180°
so, the angles are supplementary and lines a and b are parallel.
Angles 4 and 1 are corresponding angles where the line d crosses the parallel lines a and b, so are congruent.
m∠1 = m∠4 = 92°
Answer: I think d I’m not sure tho
Step-by-step explanation:
Answer:
B?
Step-by-step explanation:
Answer:
answer the cost will be higher
They are congruent because of the angles, which means the congruency reason should be SAS.
