Answer:
From the photo we can see that a pair of parallel lines are intersecting one line. BEcause those lines are parallel they form the same angles . Therefore the <1 is equal to the m<5.
A. The relationship between <1 and <5 is that they are congruent meaning they share the same angle measure.
If the m<1 and m<5 are equal then that means the equations of those anlges must also be equal:
3x+7=5x-3
Now we can solve for x
3x+7=5x-3
7=2x+3
10=2x
5=x
x=5
Therefore for question b, x=5
B. X=5
