I think the answer has something to do with math
Find A first by using formula: (a+b)/2= midpoint
so: A = [(-17)+(55)]/2
= 36
Now find B using midpoint formula:
B: (a+b)/2
=36+0/2
=18
There are a couple of things about this question that bother me.
1). BOB11111111 copied the question but didn't take the time to give us
the picture that goes with it. That bothers me.
2). If ABC is a triangle, then ABC cannot be a line. That also bothers me.
As it is, there's no way for anyone to answer the question without more
information than what we have here.
That will be 3/11.
According to your question. It is incorrect. You meant repetitive.
