Answer:
Transitive Property of Congruency;If parallel lines have a transversal, then alternate interior angles are congruent.
The Transitive Property of Congruency:
If 2 angles are congruent to a third angle, then they are congruent to each other. So, since angles 4 and 5 are both congruent to angle 1, they are congruent to each other.
Angles 4 and 5 are alternate interior angles. Therefore, if parallel lines have a transversal, alternate interior angles are congruent.
Answer: The answer is b=1/4
The dot on -1 is open, so the number -1 is not included. You need all real numbers greater than -1.
Answer: D
3x-1=20
3*7=21-1=20
The answer would be x=7
